The series from Apple TV "provides an inside look at the lives of the people who help America wake up in the morning, exploring the unique challenges faced by the women (and men) who carry out this daily televised ritual".
The trailer doesn't give fans a first-look at the cast, but instead features overlapping lines of dialogue from the three top-billed stars, designed to showcase their characters' beliefs and behind-the-scenes drama.
Aniston, Witherspoon and Carell play journalists working together on the programme. The series has been confirmed for two 10-episode seasons.
Apple has announced that the show will debut exclusively on Apple TV Plus in the autumn.
