Home Improvement is an American sitcom television series starring Tim Allen originally aired on ABC from September 17, 1991, to May 25, 1999, with a total of 204 half-hour episodes spanning eight seasons.

The series was created by Matt Williams, Carmen Finestra, and David McFadzean, and, despite not being a favorite with critics, it was one of the most watched sitcoms in the United States during the 1990s, winning many awards.

[2] Based on the stand-up comedy of Tim Allen, Home Improvement made its debut on ABC on September 17, 1991,[3] and was one of the highest-rated sitcoms for almost the entire decade.

[4] Beginning in season 2, Home Improvement began each episode with a cold open, which features the show's logo during the teaser.

In hosting this show, Tim is joined by his friend and mild-mannered co-host Al Borland (Richard Karn), and a "Tool Time girl"—first Lisa (Pamela Anderson) and later Heidi (Debbe Dunning)—whose main duty is to introduce the pair at the beginning of the show with the line "Does everybody know what time it is?"

[6] Tim and Al are caricatures of the two principal cast members of This Old House, host Bob Vila and master carpenter Norm Abram.

[7] Al has a beard and always wears plaid shirts when taping an episode, reflecting Norm Abram's appearance on This Old House.

Tim Allen, Richard Karn, Casey Sander and Debbe Dunning had a reunion in a television special named Tim Allen Presents: A User's Guide to Home Improvement in 2003 (a terminally ill Earl Hindman did voice-overs, befitting his never-seen persona of Wilson; Hindman died shortly after the special aired).

[63] Allen presented his own favorite clips from the show, insider's tips, personal reflections and a question and answer session with the live audience.

On May 5, 2015, Hollywood Life reported that Allen and Karn had admitted talking about getting back together as a cast for a Home Improvement reboot or reunion show.

[72]In January 2021, Allen reprised his role of Tim Taylor in an episode of Last Man Standing titled "Dual Time".

She cited Earl Hindman's death, Zachery Ty Bryan's legal issues, and the retirement of both Taran Noah Smith and Jonathan Taylor Thomas from acting as further reasons.
