The show was in Saturday morning syndication from October 1, 1988 to September 9, 1989, and became an instant hit. The show was expanded to five days a week and aired weekday afternoons in syndication in most markets from September 25, 1989 to March 29, 1991, with reruns airing until September 17, 1993. Starting on September 8, 1990 (with a different opening sequence), the show began its secondary run on CBS's Saturday morning lineup, beginning as a 60-minute block from 1990 to 1993, initially airing a couple of Saturday exclusive episodes back to back. There would also be a brief "Turtle Tips" segment in between the two episodes which served as public service announcements about the environment or other issues. There were at least 20 "Turtle Tips" segments that were produced and aired. Beginning in 1994, the show began airing as a 30-minute block until the series ended.
