# Advertising creative generation & testing

**Domain:** [Content & Marketing](https://www.thestateofplay.ai/domain/content-marketing) · **Tier:** Good Practice · **Trend:** Steady

AI that generates ad creative variants and tests them for performance, iterating toward higher-performing combinations. Includes automated A/B creative testing and variant generation; distinct from image generation in creative media which produces general imagery rather than performance-optimised ads.

## Overview

Advertising creative generation and testing has consolidated as mandatory operational infrastructure by September 2026, with proven production economics and scaling frameworks now diffusing across verticals—yet regulatory compliance carries measurable performance cost, platform automation has asymmetric limits on governance, and organizational capability gaps remain the primary barrier to value capture. Platform-native solutions (Google Performance Max at 43% of Google Ads spend, Meta Advantage+ ecosystem $75B+ annual run-rate) deliver strong aggregate ROAS signals and enable deployment at scale previously impossible; Skaleit's August 2026 case studies demonstrate repeatable frameworks (95% ROAS lift via ASC consolidation, 108% on 55% budget scale) and B2B viability (BuildMaster Pro: $105.88 CPL via structured asset composition). Generative AI has expanded scope from variant selection to full creative production orchestration: agentic workflows (Madgicx/Wine Mexico: 12.44x sales, 37% CAC reduction) and structured cadence-based testing (8-12 creatives/month vs 2-4) determine Andromeda recovery. Yet August–September 2026 data crystallizes four binding constraints: (1) regulatory disclosure reduces CTR 31.5% (NYU Stern/IAB), establishing permanent performance cost; (2) creative quality ceiling persists—Ipsos study (3K consumers) shows 14-17% performance gap vs human-made creative with structural reasons (AI lacks narrative arc), independent validation across multiple research firms; (3) platform automation stops at compliance—Google's video generation GA still requires manual review of brand identity, claims, and disclosures; (4) adoption plateau signals emerge—headline adoption breadth (88% of agencies) masks declining confidence (ROI perception dropped 93%→82% YoY), early regulatory tightening (Korea FTC substantiation rule Sept 3). The practice is mature on deployment economics but has hit asymptotic ROI limits; success now depends on (1) accepting regulatory/compliance cost as permanent, (2) realistic scoping of AI quality ceiling for premium categories, (3) governance investment matching automation ambitions, (4) organizational investment in creative cadence discipline and human oversight rather than platform-driven autonomy alone.

## Current Landscape

By September 2026, automated creative testing and AI-powered ad generation are mandatory operational infrastructure with documented performance thresholds, regulatory compliance costs, and asymmetric automation limits on governance. Platform consolidation: Google Performance Max at 43% of all Google Ads spend, Meta Advantage+ $75B+ annual run-rate (ecosystem-scale signal of production maturity); Google rolled out Asset Experiments feature (June 2026 GA, expanded globally Aug 2026) enabling structured testing with configurable success metrics; Microsoft AI Max GA globally (Aug 5, 2026) with text customization and Final URL expansion; Optmyzr released PMax Asset Optimization for unified asset-performance diagnostics (Aug 2026). Meta's Andromeda algorithm established creative testing velocity as primary lever: accounts shipping 8-12 creatives/month recovered to 10-15% ROAS loss under algorithm shift; 2-4/month testing lost 30-40%, establishing measurable performance gap tied to creative cadence discipline; Motion's $1.29B/578K-creative dataset confirms ~5% winner rate stable, with offer-based hooks (9.29%) and text-only formats (11.6%) outperforming production-heavy approaches, positioning testing discipline over budget size as the constraint. Real-world August–September 2026 deployments demonstrate repeatable scale frameworks: Skaleit ASC consolidation cases show 95% ROAS lift (2.61x→5.10x) and 108% lift (2.24x→4.68x on 55% budget scale) via structural discipline (strict creative rules, no budget increase); BuildMaster Pro B2B SaaS achieved $105.88 CPL via 20+ images, 5 logo variations, 3 videos in structured Performance Max; agentic workflows (Madgicx/Wine Mexico: 12.44x sales, 37% CAC reduction) demonstrate continuous testing orchestration; Aurum Lux luxury jewelry achieved 2.3x ROAS ($1.6M revenue) through dynamic creative optimization and AI-driven testing; UrbanThread DTC deployment reveals infrastructure requirements (15+ assets, 2-4 weekly production cadence required for ASC learning-phase sustainability). Yet September 2026 data crystallizes evolving constraints: (1) Regulatory compliance cost codified and immovable—NYU Stern research cited by IAB shows disclosure of AI involvement cuts CTR 31.5%, established permanent performance tradeoff under EU Article 50 and emerging US requirements (NY synthetic performer law June 9, 2026; Korea FTC substantiation rule effective Sept 3, 2026; FTC Section 5 enforcement); (2) Creative quality ceiling persists with independent validation—Ipsos study (3K consumers, 20 brands) documents 14-17% performance gap vs human-made creative, with structural cause (only 30% of AI ads employ narrative arc vs 49% human norm); Taboola field study (500M+ impressions) shows AI wins on CTR (0.76% vs 0.65%) but loses conversions 8-14% on higher-AOV products, with parity threshold rising from $25 to $100 to $200; University of Montreal confirms AI matches average human but elite creators (top 10%) significantly outperform all models; (3) Platform automation has asymmetric governance limits—Google's Multimodal Video Creation GA (Aug 27, 2026) requires manual review of brand identity, claims, disclosures, and overall quality; automation reaches storyboard/render but stops at compliance, establishing review bottleneck as non-automatable; (4) Adoption plateau signals emerge—headline adoption breadth (88% of agencies use/pilot AI creative per Straits Institute tracking, 83% of ad executives, 86% video buyers) masks declining confidence (ROI perception dropped 93% to 82% YoY per Clip Studio), 36% of consumers say AI video would lower brand perception, establishment of IPG-Omnicom autonomous-media governance office signals escalating concern over platform-driven autonomy; (5) Human capability gap primary barrier—91% of marketers abandon AI creative tasks due to poor prompt quality (57/100 C grade average); consumer perception gap widens (82% executives vs 45% consumers positive, 37-point gap). Critical adoption barriers remain organizational: real-world deployments confirm production gains only when investment flows to structured workflows (creative briefs, voice guidance, review gates, production cadence discipline) rather than tool adoption alone; high-compliance clients require human review of every asset; named DTC practitioners (Jones Road, Huron, Olipop) document brands optimizing for algorithm ROAS lose emotional resonance and repeat-purchase drivers, requiring separate brand creative track. The practice is mature on production and deployment metrics with real, measurable ROI for volume-focused, low-consideration categories, but effectiveness now explicitly contingent on: (1) accepting regulatory disclosure as permanent 31.5% CTR cost, (2) realistic scoping of AI quality ceiling (wins under $25 AOV, loses on premium; fails on emotional/storytelling briefs), (3) organizational investment in creative cadence discipline (8-12 creatives/month minimum under Andromeda), (4) governance infrastructure matching platform automation ambitions, (5) infrastructure dependencies (15+ assets, 2-4 weekly production minimum for sustained performance), (6) human oversight of autonomous platform changes rather than platform-driven autonomy alone.

## History

- **2026-Sep:** Peer-reviewed evidence sharpens on both sides of the performance question: a Journal of Marketing study finds fine-tuned Stable Diffusion outperforming human-made ads on AIDA metrics and CTR (2.04% vs 1.37%), while HBR and Marketing Science research counter that AI ads achieve visual parity but convert worse and erode consumer trust (comfort dropping 60%→46%, repurchase intent falling with delayed disclosure). Meta reports 8M advertisers using generative creative tools (up from 4M) with 22% average ROI gains, and Motion's $1.29B/578K-creative dataset confirms only ~5% of variants become winners, positioning testing discipline over budget size and governance as the top scaling blocker; Google expands Performance Max's AI video reframing to full rollout with only an account-level opt-out. Adoption breadth continues to mask eroding confidence: Clip Studio data shows video ad ROI perception dropping 93%→82% YoY even as usage rises to 33%, Straits Institute tracking confirms 88% of agencies use/pilot AI creative, and Korea's FTC substantiation rule (effective Sept 3) requires prior approval for AI-generated advertising claims. Google and Meta's autonomous agents (Campaign Agent GA, Andromeda) now run full campaigns end-to-end, with agencies reporting "competent but generic" output and IPG-Omnicom mandating weekly human review; Ipsos's 3K-consumer study reconfirms the creative-quality ceiling (14-17% lower Effect Index scores, only 30% of AI ads use narrative arc vs 49% human norm) while Google's own video-generation GA still requires manual review of brand identity and disclosures, cementing governance review as the non-automatable bottleneck.
- **2026-Aug:** Late July/early August evidence crystallizes adoption-maturity and quality-ROI gaps at scale. WARC and TikTok study (400 marketers, 88% adoption) finds only 45% report quality gains; 67% still brief AI with demographics despite 59% finding demographic targeting ineffective—showing intelligence gap limiting strategic advancement. Taboola's 500M-impression field study confirms AI creative wins CTR (0.76% vs 0.65%) but loses conversions 8-14% on higher-AOV products, with parity threshold rising from $25 to $100 to $200, establishing hard creative quality boundaries independent of platform capability. Real-world deployment failures emerge: Business Insider investigative reporting (REI, Jessica Gleim, Mediassociates) documents Meta AI creative producing distorted products and triggering feature toggles without advertiser consent, forcing new quality-control workflows across campaigns; Wonga's multi-platform experiment (Sora, Grok, Veo) yielded 400+ discarded outputs for 10 usable final ads, with documented failure modes (character consistency, dialogue reliability, context dissolution); Eco-Chic Kitchens campaign ($150k, 8-week) failed catastrophically (CTR -38.9%, CPL +90%, ROAS -65.7%, conversions -62%) due to generic AI creative and dirty data without human oversight. Independent 578K-creative benchmark (Jeena/Motion, $1.29B spend) confirms 4-8% winner rate as stable, showing testing volume (not ideation) remains the constraint. Operator consolidation strengthens: seven named deployments (iHeartMedia, Salomon, Unilever, Currys, Adore Me, Trusted Media Brands) succeed when investment flows to structured workflows (briefs, voice guidance, review gates) rather than tool adoption alone—positioning execution maturity as the differentiator. Platform evolution continues (Google VEO GA in Asset Studio, LinkedIn Brand Kit, Amazon creative tools GA) but doesn't address the operator discipline gap (only 39% of agencies significantly integrated AI vs. 90% using tools). Practice remains mandatory operational infrastructure with documented ROI for execution-mature organizations, but August evidence sharpens the bifurcation: well-structured deployments achieve 34% ROAS improvement and production-cost reductions, while poorly-governed autonomous approaches risk brand damage and negative ROAS; the gap is organizational maturity and discipline, not platform capability. Late-August evidence quantifies the regulatory-disclosure cost directly: NYU Stern research cited by IAB confirms disclosing AI involvement cuts CTR 31.5%, while an IAB/Sonata survey documents a 37-point executive-consumer perception gap (82% vs 45% positive) despite 73% consumer acceptance when disclosed. Meta's Andromeda algorithm hardens creative-cadence discipline as the primary recovery lever (8-12 creatives/month recovers 10-15% ROAS loss vs. 30-40% loss at 2-4/month), and new named case studies (ASC consolidation delivering 95% and 108% ROAS lifts; Madgicx/Wine Mexico agentic deployment at 12.44x sales, 37% CAC reduction; BuildMaster Pro's $105.88 CPL via 20+ asset variations) reinforce testing-orchestration and asset-production infrastructure as load-bearing constraints.
- **2026-Jul:** Early July independent data validates market pressures alongside deployment successes. Channable's €1.38B verified spend analysis documents +15% cost-per-click YoY and -46% average ROAS contraction on Performance Max (€1.44 CPA increase) vs. June 2025, showing adoption barriers and market saturation pressures outpacing productivity gains. Google PMax Q3 algorithm change (early July) caused sharp ROAS declines (4–5x down to 2–3x in three weeks across apparel, home, beauty) by reweighting budget allocation toward lower-ROI placements, documenting platform-optimization risk and dependency vulnerability. Yet deployment validation continues: Virgin Atlantic achieved 9.2x ROAS with 70% lower CPC through Performance Max consolidation and asset-group segmentation. Consumer trust erosion sharpens organizational barriers: Klaviyo data shows only 13% full consumer trust in AI content, Gartner finds 50% prefer brands avoiding AI, and Supermetrics survey (435 global marketers) confirms 50% using AI for creative but only 37% planning testing investment—signaling adoption scaling faster than organizational maturity. Practice sustains mandatory-infrastructure status with validated deployment ROI, but early-July data crystallizes two asymmetries: independent cost-pressure validation (Channable) against platform claims, and consumer-trust erosion (13% full trust) against technical maturity (87% unable to identify AI), positioning effectiveness as increasingly dependent on organizational execution over platform capability. AI-generated UGC has also become cost-competitive: a July 2026 DTC playbook documents $5-40 per asset (vs. $200-800 for traditional production) with output indistinguishable from real UGC in 90% of cases for volume testing and hard-to-shoot scenarios, though it still fails for hero creatives and sophisticated audiences.
- **2026-Jun:** Platform deployment economics crystallize at scale: 4M advertisers using Meta generative tools, AI-generated creatives delivering 47% CTR lift and 29% CPA reduction in aggregate adoption data; Zencastr case study drops CAC 92% ($34→$2.59) by scaling to 40+ AI variants per sprint; app brands (Funsol, SeaBank, Falcon) achieve 46x daily asset volume and 100K+ variations/month at 79% benchmark hit via Gemini; Bark Avenue drops CPA $38→$24 (36%) through structured asset-group testing. Google Asset Experiments feature reaches GA (June 2026) enabling configurable element testing within Performance Max. IAB documents 83% of ad execs deploying AI in creative process (up from 60% in 2024), but Forrester analysis of 90% agency adoption finds 81% prioritise cost reduction over creative quality — the explicit finding that AI adoption is undermining creativity and long-term brand growth sharpens the strategic tension. Regulatory compliance codified: NY synthetic performer law (effective June 9) and EU AI Act Article 50 (effective August 2) mandate AI-generated media disclosure; CA SB 942 and FTC Section 5 add further compliance layers — mandatory disclosure now reduces ad effectiveness by ~31.5%. Creative quality ceiling confirmed again by Ipsos/Syracuse peer review: AI ads under-index 5 points despite 87% consumer inability to identify AI origin, with performance gap widening on emotional briefs.
- **2026-May:** Google AI Max expands with AI Brief, video voiceover generation, and Shopping campaign coverage; Asset Studio upgraded with Gemini Omni video creation and 1-click creative testing (creative drives 49% of incremental sales). WFA research shows 78% of multinationals deploying AI-generated creative (78% of marketing teams overall, up from 41% in 2024), with 61% citing transparency gaps. Peer-reviewed evidence hardens creative quality ceiling: Ipsos + Syracuse University study (3,000 respondents, 10 brands) finds AI ads under-index by 5 points vs. human (+11 points) despite 87% of viewers unable to identify AI origin, failing on emotional/storytelling briefs; University of Montreal (100,000+ humans vs GPT-4/Claude/Gemini) confirms AI matches average human creativity but top 10% of humans significantly outperform all AI models. Real-world agency deployments show production gains (Monolith KLH: 40-60 variants/month, <24-hour turnaround, 25-30 hours/week recovered) with Google eCom Lab patterns (margin-tier optimization +22% ROAS, feed quality 15-30% impact) and L'Oreal doubled conversion rate via AI Max. User capability gap emerges as primary barrier: Adobe study finds 91% of marketers abandon AI creative tasks, average prompt quality 57/100 (C grade). AOV performance splits confirmed: AI wins under $25 (4.8x vs 4.5x ROAS) but loses on premium over $500 (2.3x vs 3.1x human). Practice consolidates as operational infrastructure with measured capability gains, but deployment effectiveness remains highly dependent on advertiser execution maturity, budget scale, and brand category fit.
- **2026-Apr:** Google PMax shifts to asset-level creative review (replacing campaign-level enforcement), enabling rapid testing cycles with 0-60s text processing and 2-4h image/video review. Advantage+ ROAS benchmarks confirmed at 4.52x (22% above manual) across 50K+ campaign dataset. Practice consolidates at institutional maturity with proven value for performance-optimized verticals (impulse, low-consideration), but quality constraints and consumer perception barriers sharpen boundaries around brand-building and premium categories.
- **2026-Mar:** Governance and quality control frameworks emerge as core practice infrastructure. Advertising Association publishes 8-principle best-practice guide (transparency, bias prevention, human oversight, brand safety); Google and Meta enforce AI content disclosure policies. Google AI Max Text generation hits GA to all advertisers with 14% conversion lift. Critical independent assessments deepen: Kantar's database shows GenAI-created ads score 54th percentile vs 65th for non-AI (average), documenting fundamental creative quality challenge; Digital Applied's 50K+ variation dataset confirms -8% to -14% conversion penalty on high-AOV products and 17% lower purchase intent when AI-identified. Advanced Science peer-review finds unguided AI significantly underperforms human artists on creativity tasks.
- **2026-Feb:** New real-world deployments and adoption data confirm platform maturity with critical execution boundaries emerging. Joybird achieved 40% ROAS lift and 95% revenue increase with Performance Max in controlled testing (Feb 2026). Adoption continues: 71% of advertisers use Performance Max (up from 60% in 2024), with platforms delivering 51B impressions and 19.9% spend growth. However, nuanced analysis reveals automation works within bounds: Advantage+ outperforms manual at high budgets ($3K+, 23% higher ROAS) but underperforms at low budgets (31% worse), exposing deployment threshold constraints. Negative evidence surfaces: Performance Max guidance fails new advertisers due to reduced control and data-quality dependency. Efficiency gains quantified: hybrid AI-scripted creative production achieves 280% output increase and 65% cost reduction, but critical assessments document AI creative limitations including lack of originality and quality concerns. Practice reaches inflection point where adoption scales but effectiveness becomes increasingly contingent on advertiser sophistication and proper configuration.
- **2026-Jan:** Peer-reviewed research (Université de Montréal) validates AI exceeds average human creativity but cannot match elite creators. Platform evolution accelerates: Meta launches 2026 feature updates with Predictive Budget Allocation (8-15% ROAS gains) and video generation (40% cost reduction); Google adds A/B testing features for Performance Max. Real deployments continue (digital agencies document 623% purchase increases, 7.69 ROAS). Yet execution gap crystallizes: FreeWheel survey reveals 61% of advertisers report no meaningful results from AI creative tools despite 41% adoption. Only 29.7% have moved AI creative to production; data quality and integration barriers affect 42-41%. AI-generated video adoption accelerates to 57% of online ads. Practice consolidates at mandatory operational status but reveals severe organizational capability gaps and uneven value delivery.
- **2025-Q4:** Meta's GEM and Lattice AI systems achieve production-scale deployment: 5% conversion lift (Instagram), 3% (Facebook), 12% ad-quality improvement. Google Performance Max maintains 43% spend share; FULLBEAUTY Brands achieves 45% ROAS lift with AI-generated creative variations. Yet platform-contradiction surfaces sharply: Wicked Reports analysis of 55,661 campaigns shows Advantage+ new customer acquisition cost doubled ($257→$528) between May 2024-2025. IAB survey reveals 58% plan increased AI creative investment, but 70%+ already encountered incidents (hallucinations, bias, off-brand); only 35% plan governance investment. Practice reaches institutional maturity—mandatory infrastructure for competitive positioning—but Q4 data exposes widening gap between platform ROAS claims and real-world incremental performance, with advertiser success contingent on implementation excellence and data maturity.
- **2025-Q3:** Meta unifies Advantage+ API (May 2025, rollout through Q1 2026) to streamline campaign creation via automation. Fortune 500 adoption reaches 78% in marketing/comms (matched with IT/engineering). Video creative generation accelerates—30% of digital video ads powered by GenAI in 2024, projected 39% by 2026; small brands lead with 45% AI-built creatives expected by 2026. Yet critical failures emerge: growth marketing veteran documents pulling all clients from Performance Max after incrementality tests show <10% incremental revenue vs. 80-90% for non-branded search, challenging platform ROAS claims. BCG analysis reveals limited enterprise deployment of GenAI in creative development despite momentum, citing glitches, crashes, and process rethinking requirements. Practice stabilizes at operational maturity but reveals deployment fragmentation: headline adoption metrics mask real-world incrementality gaps and consumer perception risks around AI-generated advertising.
- **2025-Q2:** Adoption infrastructure reaches scale: Meta Advantage+ 4M advertisers globally (70% YoY growth); Advantage+ $4.52 ROAS (22% higher than traditional). KPMG survey shows 93% leadership confidence in GenAI ROI, with AI-agent piloting accelerating to 65%. Yet independent research reveals deployment reality: only 4% of orgs achieve consistent GenAI value, 68% moved less than a third of experiments to production, 11% at scale adoption (UC Berkeley CMR). Optmyzr study of 24.7K Performance Max campaigns confirms widespread use (82% run alongside other channels) but performance variance due to setup/creative quality. Kantar validates hybrid testing with Unilever case showing 57% asset coverage with AI. Deployment maturity increases but strategic fragmentation widens between high-performing deployments and majority struggling with basics.
- **2025-Q1:** Performance Max reaches 43% of all Google Ads spend (up from 22% in 2023), signaling platform shift toward mandatory AI-driven creative optimization. Independent validation (Kantar LINK AI) confirms 80% prediction accuracy and 15x sales lift for top-performing ads. Yet adoption remains fragmented: only 30% of enterprises have fully integrated AI in campaign lifecycles (IAB survey). Marketer adoption sentiment shows friction: 38% uncomfortable with AI-generated creative in production (Marketing Dive), citing consumer perception risks highlighted by neuroscientific research. Practice crosses production maturity threshold with measurable business returns, but deployment challenges sharpen around data quality, platform lock-in, and consumer backlash to AI-generated ads.
- **2024-Q4:** Meta's Andromeda AI system reaches production scale, driving 22% ROAS gains for Advantage+ adopters; Meta aggressively pushes platform-default automation, reducing advertiser control. Real deployments continue (Arta Tradiției: 251% conversion lift; Trellis: 60% CTR gains with AI image generation). However, critical December 2024 neuroscientific research (NielsenIQ BASES) reveals AI-generated ads elicit weak memory activation and negative consumer perception—a counterweight to optimization gains. Optmyzr's 9,199-account study shows strategy-dependent performance: configuration and data quality determine success; 55% of accounts don't meet conversion thresholds. Creative automation is now standard operational practice, but effectiveness is constrained by consumer perception risks, data infrastructure dependency, and platform-driven loss of advertiser autonomy.
- **2024-Q3:** Google expands creative asset generation and reporting to App and Display campaigns (July 2024), moving beyond Search-only. Performance Max deployments continue across recruitment and consumer verticals. Standalone AI creative tools (AdCreative.ai) mature as accessible alternatives to platform-native solutions. Creative testing methodology solidifies as standard practice rather than bleeding-edge innovation. Underlying tension persists: platforms deliver measurable ROAS but field evidence continues to show data-quality dependency and algorithmic brittleness in complex scenarios.
- **2024-Q2:** Google launches AI-powered creative asset generation, brand guideline integration, and image editing for Performance Max (5x faster production reported). Agency adoption reaches 91% (Forrester), with 49% using generative AI for dynamic asset optimization. Meta commits to full creative automation by 2026 at Performance Marketing Summit. However, critical field assessments surface persistent problems: hotel campaigns show 95.7% brand keyword cannibalization despite algorithmic promises, and invalid bot traffic affects 5-15% of search clicks. Tension sharpens between genuine creative improvement and algorithmic spend reallocation.
- **2024-Q1:** Performance Max and Advantage+ move to production-at-scale with exceptional deployment metrics across consumer verticals (839% ROAS, +32% ROAS improvements documented). Industry adoption broadens: 78.2% of 3,000+ retail campaigns use AI-driven Target ROAS bidding. Both platforms commit to full automation (Meta targeting fully automated AI-driven ads by 2026). Critical assessment emerges: practitioners document persistent data transparency and creative-quality evaluation limitations alongside real business wins, sharpening the distinction between algorithmic spend optimization and genuine creative improvement.
- **2023-H2:** Generative AI enters ad creative ecosystem via Meta's AI Sandbox and AWS SageMaker, expanding creative testing from variant selection to full creative generation. Mainstream adoption accelerates (83% of creative professionals using ML tools by Nov 2023). Performance Max faces real-world criticism for performance mixing and algorithmic opacity, whilst practitioners develop systematic diagnostic frameworks for troubleshooting campaigns. Creative testing becomes institutionalized as structured methodology across platforms.
- **2023-H1:** Google Performance Max and Meta Advantage+ establish mainstream automated creative testing and variant selection. Early deployments show strong ROAS improvements (KEH Camera +76.5%, Culligan franchises with sustained gains), yet adoption remains concentrated among performance-focused advertisers and agencies. Privacy restrictions and cultural resistance to algorithmic creative control remain barriers.
