The ITV game show 'Tenable,' hosted initially by Warwick Davis and later by Sally Lindsay, is rumored to be canceled after seven successful series. Despite having a backlog of episodes to air soon, there are no plans for new episodes, and there have been no recent calls for contestants. The show featured teams of five attempting to complete category lists for a chance to win up to £125,000. Warwick Davis had taken a break from the show for a secret project before his wife Samantha's tragic death earlier this year at age 53. Meanwhile, Ken Bruce's 'PopMaster TV' has been renewed for a third and fourth series, continuing its success on Channel 4. The music quiz show, which tests contestants' knowledge of popular music, has opened applications for new participants and will be filmed in Glasgow.
