NBC has announced a special primetime network broadcast of "Merv Griffin's Crosswords". The show will air one time only on Saturday, September 8 at 8:30 p.m. (NBC publicity simply titles the show "Crosswords". Hmmm....
This is similar to a stunt MyNetwork is running to promote Twentieth Television's "Temptation", by giving that new syndicated show a network window.
"Crosswords" will begin airing in syndication on September 10, and syndicator Program Partners has announced that a whopping 225 episodes will be produced during the first season to keep repeats to a minimum.
UPDATE: Due to an NBC scheduling change, the prime-time broadcast of "Merv Griffin's Crosswords" has been cancelled. It will still begin in syndication on September 10, but will just not have the primetime preview.
