This week, Apple announced Apple TV+, a new streaming service coming from the tech giant this fall. While many details surrounding its debut remain under wraps, the Silicon Valley juggernaut was sure to highlight its star power during a presentation at Apple headquarters in Cupertio, CA Monday night.

The Verge reports Oprah Winfrey closed out the Apple new services presentation with the announcement of two new documentaries being brought to Apple TV+. Toxic Labor will tackle workplace harassment while a second multi-part series will focus on mental health. According to the media mogul, she’s partnering with Apple because “the Apple platform allows me to do what I do in a new way.”

Winfrey also has plans to develop, "the biggest, most vibrant, most stimulating book club on the planet... I want to literally convene a meeting of the minds connecting us through books."

Apple will also team up with other big names such as Steven Spielberg, Jennifer Aniston, Reese Witherspoon and Octavia Spencer.

“We’re honored that the absolute best lineup of storytellers in the world — both in front of and behind the camera — are coming to Apple TV+,” said Eddy Cue, Apple’s senior vice president of Internet Software and Services. “We’re thrilled to give viewers a sneak peek of Apple TV+ and cannot wait for them to tune in starting this fall. Apple TV+ will be home to some of the highest quality original storytelling that TV and movie lovers have seen yet.”

Apple has yet to announce the Apple TV+ price or exact premiere date.
