Joker's Wild - the last CBS year for several months leading up to the '77 revival
IIRC, The Jokers Wild CBS rerun package was still in syndication beyond 1977, and perhaps up until '79 or '80. I also want to say, based on fuzzy memory, that Play The Percentages replaced CBS Joker reruns or vice-versa, at least in Cleveland.
The CBS reruns aired weekday mornings in the 9AM hour before the CBS daytime game shows at 10AM on WJKW/TV-8. The new first-run syndicated Joker shows aired in the early prime during the 7PM hour.
