I know that first-run episodes ceased production (https://www.sitcomsonline.com/boards/showthread.php?t=381088) after the 1988-89 season. And I previously made a thread (https://www.sitcomsonline.com/boards/showthread.php?t=394783) about the stations that aired it in syndication beginning in 1985-86. I read (https://officialfan.proboards.com/thread/627664/classic-tv-surprised-staying-power) that the reruns became a stable in daytime television throughout the '90s.
