Increasingly Complex Environment

Shifting demographics and the advent of digital technology have fundamentally changed the discipline of marketing and created a more complex and fragmented environment for clients and consultants.

Oct 21, 2026 - Digital Advertising Complicates Traditional Marketing Strategies

• The advertising industry's shift from traditional television to digital platforms is giving marketing consultants more ways to reach consumers, but also making campaign planning more complicated. Streaming services, social media, and retail media networks offer better targeting and more measurable results than conventional TV commercials, requiring consultants to rethink how clients allocate their advertising budgets. According to the Interactive Advertising Bureau, US social media advertising spending is expected to grow 16.5% in 2026, while connected TV spending will jump 15.6%. Meanwhile, linear television advertising is projected to decline 1.5% as viewers continue abandoning cable and satellite subscriptions. Digital video is expected to capture more than 60% of all US television and video advertising spending this year. Still, traditional TV remains relevant. EMARKETER expects it to attract more than $50 billion in advertising in 2026, particularly around live sports and major events.
• Marketing professionals face growing pressure to help businesses separate AI hype from measurable results as spending on the technology outpaces companies' ability to use it effectively. Gartner reports that marketing executives are allocating 15.3% of their budgets to AI initiatives in 2026, yet 70% say their organizations lack the processes needed to implement the technology successfully. Consumer skepticism presents another obstacle. Kantar's 2026 research found that just 24% of consumers trust brand recommendations from AI assistants, even as marketers plan to boost investment in the emerging channel. Advertising effectiveness also remains uncertain, with limited targeting controls and questions about brand safety complicating AI-driven campaigns. Meanwhile, Gartner found that 38% of marketing executives cite a shortage of AI expertise as their biggest barrier to improving efficiency, creating opportunities for companies that can demonstrate tangible returns on technology investments.
• 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.
