On May 1, the 5:00 PM and 5:30 PM airings of Match Game moved to 1978 (from 1977), four weeks after Dawson's departure.
On May 4, the 9:30 AM airing of Supermarket Sweep moved to 1994 episodes (from 2000). These appear to be from early in the season, as David is emphasizing the then-new $250 Super Bonus. The production numbers from Buzzr's schedule do jump around a little bit (This week, for example, is 1394, 1403, 1396, 1401, and 1398).
