The Taylor Swift/Travis Kelce effect demonstrates the power of combining disparate audiences.

The NHL saw a significant boost in ticket sales from first-time buyers on platforms like StubHub, directly tied to the popularity of the HBO Max show "Heated Rivalry."

Instead of a standard celebrity ad, The Gap produced a full-fledged music video with the group Cat's Eye, generating 500 million views. By creating culture (art, music) instead of just sponsoring it, The Gap transformed its marketing from an expense into a viral entertainment asset, driving its best growth in years.

The success of events like the Daft Punk concert in Fortnite signals a strategic shift. IP holders will launch new brands within games first to build community, then expand to movies or TV. Games are now viewed as the most influential social platforms, not just secondary marketing channels.
