Big Brother: Over the Top (or BBOTT for short) is a spin-off American reality television series of the show Big Brother that aired exclusively online. The season premiered on September 28, 2016 and ended after 65 days with a season finale on December 1, 2016 only on CBS All Access, an over-the-top subscription streaming service. The season was officially announced by CBS on August 3, 2016, while Big Brother 18 was still in progress.
As with the televised series, the group of contestants—referred to as HouseGuests—are enclosed in the Big Brother House under constant surveillance of cameras and microphones. Each week a HouseGuest was evicted until the final three HouseGuests remain on finale night. Unlike in Big Brother, the viewers voted to crown a winner. Julie Chen hosted the season premiere and finale, and conduct weekly eviction interviews. In the season finale, the voting public awarded Morgan Willett with the $250,000 grand prize over Jason Roy and Kryssie Ridolfi.
The season was officially announced on August 3, 2016 by CBS while the eighteenth season was still in progress. The series continued to air on the CBS television network during the summer while the fall edition aired exclusively on the over-the-top streaming service CBS All Access which has been the broadcaster of the live Internet feeds since the seventeenth season. The season would utilize the same production team from past seasons with executive producers Allison Grodner and Rich Meehan for Fly on the Wall Entertainment in association with Endemol Shine North America. Julie Chen, who has been the host of the series since its inception, would also be part of this season. However, Robyn Kass, who has cast the program since the second season, would not cast this season. The shortest season since Big Brother 10, the season only lasted nine weeks. This was the first edition of the Big Brother franchise to air live exclusively online around the world and the second season overall to air only online after the first Chinese season, which was pre-recorded and aired at a later date in 2015.
