Other productions
From 1995 to 1997, Roth co-hosted The Disney Channel's Walt Disney World Inside Out along with Brianne Leary and George Foreman.
While not working on Endurance, Roth serves as narrator on NBC's weight loss reality show, The Biggest Loser (with Caroline Rhea and, later, Alison Sweeney), which he also co-created and produces. He also produces reality shows Breaking Bonaduce, with Danny Bonaduce on VH1 and Beauty and the Geek on the CW Network, alongside Ashton Kutcher.
On September 23, 2008, ABC premiered Opportunity Knocks, which received low ratings, especially in the 18-34 demographic, and was canceled after three episodes. ABC subsequently scheduled the remaining six completed episodes for broadcast, beginning on May 26, 2009.
Roth's 3Ball Productions has partnered with Milestone Entertainment to produce the California Lottery's new game show, Make Me a Millionaire, which premiered on January 17, 2009, for an initial four-year run, but was canceled due to poor ratings; the last program was on July 3, 2010.
He hosted and co-created Unan1mous, which premiered March 22, 2006. Though the show did well in the ratings, possible high production costs kept it from getting a second season.
In September 2006, the Dutch company Eyeworks Group announced that it had acquired a 50-percent ownership of 3Ball Productions. He also produced the ABC game show Downfall, which aired in the summer of 2010. Hosted by wrestler Chris Jericho, the show featured contestants answering trivia questions to stop valuable prizes from falling from the roof of a Los Angeles building.
Beginning in 2011, Roth served as producer for the Spike reality show Bar Rescue. As of August 2024, the show has aired nine seasons.
