District 31 (2016-2022)

Based on an international hit, which already is a viral phenomenon with more than half a billion fans worldwide, and the No. 1 top-trending video of 2017 on YouTube, The Masked Singer features celebrities facing off against one another with one major twist: each singer is shrouded from head to toe in an elaborate costume, complete with full face mask to conceal his or her identity. Ken Jeong, Jenny McCarthy, Nicole Scherzinger and Robin Thicke serve on the panel and play detective, alongside host Nick Cannon.

The Floor is a physical quiz show that sees 81 contestants face off in quiz duels on a giant LED floor divided into a 9×9 grid of squares, each representing its own field of knowledge.

The first challenger, selected at random, must choose one of his or her neighboring opponents to go head-to-head in an epic quiz duel in the opponent's category. The winner takes over the loser's square, gaining valuable ground as they expand their territory, while the loser exits the game. The winner must then choose – do they continue on and attempt to secure another square? Or do they let The Floor choose a new challenger? The last contestant standing who gains full control over The Floor takes home a life-changing $250,000 cash prize.

Garvin, Troy Johnson, Catherine McCord, Aarti Sequeira, among others. The last chef standing goes on a shopping spree of a lifetime worth up to $20,000!
