# Millennial-era franchise IP has a structural demographic ceiling among Gen Z because the formative community experiences that created Millennial franchise fandom did not occur for Gen Z

YPulse's March 2026 analysis frames the generational franchise gap as 'does Gen Z even care' rather than 'does Gen Z love it less,' suggesting a qualitative difference in relationship rather than quantitative affinity decline. Morning Consult data shows Gen Z adults at 15% avid Harry Potter fans versus Millennials far above all other generations (Gen X 19%, Boomers 14%). The mechanism is timing-based: Millennials experienced Harry Potter's 1998-2011 cultural arc as formative events—midnight book releases, packed movie premieres, years of culturally built hype—while Gen Z encountered the same IP as established legacy content without the collective community-building moments. YPulse notes 'interest in franchise products has steadily declined over the years' and applies the same pattern across Marvel and Jurassic Park. This is not a marketing problem but a structural timing gap: the multiple reinforcing exposures that form complex contagion-based fandom never occurred for Gen Z in their formative years. The upcoming Harry Potter TV show on MAX represents a natural test case—if it successfully reactivates Gen Z community formation, it would challenge this structural ceiling thesis.
