Have you seen that new Apple TV+ ad with Timothée Chalamet? The young star is bummed that he’s not part of its A-list programming, reminding everyone that Ted Lasso, projects from Selena Gomez, Jennifer Lawrence, Martin Scorsese and Leonardo DiCaprio, Jason Momoa, and last year’s best picture winner, CODA, can or will soon be found on Apple TV+. Yes, Timmy keeps telling us, on Apple.

It’s a classic branding ad—you can almost hear Apple’s services guru Eddy Cue screaming like he’s courtside at a Warriors game: We’re Apple, dammit! Check out who we’re working with! Big f-ing stars, OK?! Not like those regular streaming services. And there’s data behind the specific messaging. As the second part of Puck’s streaming brand study reveals, consumers have a really tough time remembering where particular shows and movies are available, even if they have watched those shows and movies. It’s called “recall,” meaning how well people connect specific content to a specific platform, and it’s a big problem for these services as they try to distinguish themselves in a crowded market.
