From the most recent Buzzr newsletter.
Notably, one question asks if you'd like to see the following shows on Buzzr, with the below shows mentioned (anything in (parentheses) was part of the listed name):
To Tell The Truth
...so what is airing on the channel currently at 8PM EST daily...and at 4AM.....
Seeing the list of potential shows out of the 90s and aughts, It wouldn't surprise me if they might be considering dusting off the NBC Daytime TTTT and/or the O'Hurley syndicated versions.
Celebrity Name Game
Hollywood Squares (90s version)
Both already have their own FAST/Streaming channels.
Now if BUZZR would consider replacing MGHSqH with Ross Shaffer's MG and John Davidson's HSq, I would call that an (slight) upgrade.
