# Gen Z leads the generational shift toward AI content rejection

The IAB data reveals a significant generational divide in attitudes toward AI-generated advertising content, with Gen Z demonstrating substantially more negative sentiment than Millennials across all measured dimensions. Gen Z shows 39% negative sentiment toward AI ads compared to 20% for Millennials, a gap that widened from the 2024 baseline of 21% vs 15%.

The generational differences are even more pronounced on specific brand attribute perceptions. Gen Z rates AI-using brands as inauthentic at 30% versus 13% for Millennials (2.3x higher); as disconnected at 26% versus 8% (3.25x higher); and as unethical at 24% versus 8% (3x higher). These gaps suggest Gen Z has a more developed framework for evaluating AI content and applies stricter standards around authenticity and ethics.

This data indicates Gen Z serves as a leading indicator for the entertainment industry. As this cohort ages into primary spending power and influence, the current negative sentiment patterns among Gen Z are likely to become industry-wide norms. The magnitude of the gap (roughly 2-3x on key attributes) and the widening of the generational gap from 2024 to 2026 (6 points wider on overall negative sentiment) suggests this is not a temporary cohort effect but a durable shift in how younger consumers evaluate AI-generated content.
