Now in its 20th season, "The Simpsons" already had tied record-holder "Gunsmoke." The Western drama series aired for two decades on CBS before it ended in 1975.
"The Simpsons" will pass that mark next season. The two-year, 44-episode pickup announced Thursday by Fox will bring the total number of "Simpsons" episodes to 493.
The animated comedy about Homer and Marge Simpson, their children and the town of Springfield is not only enduring but much-honored: It's received a Peabody and 24 Emmys among other awards.
