Other game shows produced by the team included Chain Letter, Three for the Money and It's Anybody's Guess for NBC and It Pays to Be Ignorant and Masquerade Party in syndication.

In 2021, the holding company was acquired by Marcus/Glass Entertainment, a joint venture of Nancy Glass and Marcus Lemonis, with Sharon Hall Kessler, a former Endemol Shine executive, as consultant.
