The word '''Improvathon''' is a portmanteau of the words ''improvisation'' and ''marathon'' and is used to describe an extended performance by a team of improvising performers. The format establishes a group of characters early on, who become part of a continuous plotline. Commonly, as well as scenes which progress the story, performers may participate in musical numbers and other challenges or games. The action is directed for both performers and audience by writers who develop the plot in response. Whilst some performers may take a break at some point during the event, traditionally some core cast members will participate for the entire duration, going one or two nights without sleep. The sleep deprivation reduces performers to their "lizard brain" state, where they become too tired to censor themselves, resulting in a unique and euphoric form of theatre. Many audience members stay for the full duration, sharing the sleeplessness with the actors. In Edmonton, Canada, where the concept was originally devised, it is known as a Soap-A-Thon.

==Soap-A-Thon==

The Soap-a-thon has most notably been made popular by Canadian improv company Die-Nasty who completed their first 50-hour Soap-A-Thon in 1993 at the Varscona Theatre. They have produced further Soap-A-Thons every year since.<ref>http://www.korymathewson.com/2009/09/soapathon/{{Dead link|date=November 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref>{{Cite web |url=http://www.casaannett.com/varsconatheatre/die-nasty/Die-Nasty_Web/Home.html |title=Die Nasty the Legendary Live Improvised Soap Opera! |access-date=2010-12-05 |archive-url=https://web.archive.org/web/20110122052201/http://www.casaannett.com/varsconatheatre/die-nasty/Die-Nasty_Web/Home.html |archive-date=2011-01-22 |url-status=dead }}</ref>
