Witherspoon and Jennifer Aniston stepped up to intro their series, The Morning Show, joined by co-star Steve Carell. Jason Momoa exploded on stage to talk about his project See, in which the human race collectively loses its sight, while Kumail Nanjiani outlined his anthology series Little America

The parade of luminaries was rounded out by Big Bird, announcing a new kids show from the makers of Sesame Street, followed by Sara Bareilles singing the theme song for her show Little Voice.

Apple CEO Tim Cook then returned to the stage to emotionally introduce one more voice: Oprah Winfrey, who is producing two documentaries and a book club for the streaming service.

Apple is reported to be betting $1 billion on the streaming service in a challenge to rivals Netflix and Amazon. We'll see that money up on the screen in shows by Apple's army of big names, which also includes launch event no-shows Ron Howard, M. Night Shyamalan, Damien Chazelle and Sofia Coppola. Guess they were busy being not quite famous enough.
