I’m pretty sure I’ve told these stories before, but just in case.
One day my brother and his then girlfriend were over in the afternoon and at the time, GSN had the original Card Sharks and the Eubanks CS back to back. She got into the much more subdued nature of the 1970s series, but wasn’t impressed with the look in the 1980s.
With my other brother, once we finally got GSN, the daily airing of the syndicated CS was as close to appointment TV for us as we could get. So much so that when they dropped it and brought back the CBS episodes, the first question he asked was “where are the prize cards?” I had to explain that it was a gimmick just for the other show.
