Overview and Answer Summary
Three's Company aired from March 15, 1977 to September 18, 1984, spanning 8 seasons and 172 episodes. It was a United States sitcom that ran on ABC and became one of the top-rated comedies of the late 1970s and early 1980s. The series was based on the British show Man About the House and followed three single roommates—Jack, Janet, and Chrissy—navigating life, love, and misunderstandings.
This evergreen explainer clarifies when the show aired, its broadcast schedule, and key milestones so readers can quickly understand its timeline and factual status.
Premiere and Finale Dates
Three's Company premiered on March 15, 1977, and its final original episode, the series finale, aired on September 18, 1984. These dates define the show's on-air lifespan on ABC, covering most of the 1970s and the early part of the 1980s.
Neither the premiere nor the finale were midseason replacements in the usual sense; the premiere launched in primetime, and the finale concluded after eight seasons without a direct series continuation on broadcast TV. Exact air dates varied slightly by market, but March 1977 and September 1984 reflect the network-wide schedule.

Post-Original Run and Syndication
After its 1984 finale, Three's Company entered syndication and remained a staple of rerun packages for decades. The show was also continued with a sequel series, Three's a Crowd, which ran for one season (1984–1985) and starred John Ritter and Amy Yasbeck without Janet or Chrissy. There were no official seasons, episodes, or network renewals beyond the ABC run, since it was a continuation rather than a direct reboot.
