Sep 16, 2026 - AI Deepfakes Complicate Brand Management

• Deepfakes are creating a new challenge for marketing consultants as AI makes it easier to convincingly copy a real person’s face, voice, or mannerisms without permission. The problem extends beyond fake celebrity endorsements: brands can find their executives, employees, influencers, or spokespeople inserted into content they never approved, while legitimate AI-generated campaigns can face questions about whether consumers are being misled. The FTC says using a celebrity avatar without permission can violate its consumer testimonial rule when viewers could reasonably believe the person endorsed the product. States are also expanding protections for digital replicas, although requirements vary widely. That is broadening the role of marketing consultants, who may be called on to help clients establish rules for AI-generated content, verify outside creative work, secure appropriate likeness rights, and prepare for deepfake incidents that could quickly become brand crises.
• Advertisers are spending more this year, but that extra money isn’t flowing evenly across the industry. Instead, marketers are putting more of their budgets into channels where they can target specific audiences, adjust campaigns quickly, and get a clearer read on what’s working. According to the Interactive Advertising Bureau (IAB), US ad spending is projected to rise 9.5% in 2026, with social media (+14.6%), connected TV (+13.8%), and commerce media (+12.1%) leading the way as traditional channels lose ground. Digital video alone is expected to top $80 billion and capture more than 60% of TV/video ad spending for the first time. For agencies, a bigger advertising market won’t necessarily lift everyone equally. Firms with strong digital, targeting, and measurement capabilities are in a better position to follow the money as advertisers concentrate more of their budgets in a handful of fast-growing channels.
• Marketing consultants are being pushed to rethink how campaigns are built as consumers bounce among streaming, social media, retail platforms, and other channels throughout the day. Rather than creating one big campaign idea and trimming it down for different outlets, brands are moving toward “connected content,” where creative deliverables change based on consumer behavior, context, and timing. Omnicom Media Intelligence found that 80% of consumers say a bad ad is worse than no ad at all, while 84% connect with advertising they consider relatable and 78% respond to ads that reach them at the right moment. That puts more pressure on consultants to bring creative and media planning together earlier and use data to adjust campaigns as they run. It also changes the consulting job itself, with more emphasis on auditing disconnected marketing processes and helping clients build systems that can react faster to what consumers are actually doing.
• Brands are putting more money back into live events as they look for ways to stand out in an increasingly crowded digital marketplace. Trade shows, pop-up shops, sponsorships, and experiential campaigns are taking a larger share of marketing budgets, creating new demand for consultants that can tie in-person experiences to broader brand and customer engagement strategies. The Content Marketing Institute found that 78% of B2B marketers now allocate part of their budgets to experiential marketing, with nearly 40% dedicating up to 10% of total marketing spending to those efforts. Meanwhile, the Center for Exhibition Industry Research forecasts the US business-to-business exhibition industry will grow another 2.1% in 2026 as attendance and exhibitor participation continue to recover. Consultants are increasingly being asked not only to design these campaigns, but also to prove their return on investment by measuring lead generation, customer engagement, and sales outcomes.
