( UK TV series ) External links Website www.cwtv.com/shows/whose-line-is-it-anyway Whose Line Is It Anyway ? ( often known as simply Whose Line ? ) is an American improvisational comedy show, which was originally hosted by Drew Carey on ABC and ABC Family and ran from August 5, 1998 to December 15, 2007. A revival of the show, hosted by Aisha Tyler, began airing on The CW on July 16, 2013. The series is an official adaptation of the British show of the same name and features Ryan Stiles, Colin Mochrie, and Wayne Brady as its regular performers with the fourth seat occupied by a guest panelist. All three regulars appeared on the British series ; Stiles and Mochrie were both regulars ( first appearing in the second and third series ' respectively, and both appearing in every episode from series 8 onwards ), with Brady a frequent guest in the final series which moved production from London to Hollywood. Ryan Stiles is the most prolific performer in the history of Whose Line ?, having made 76 appearances in the British version, and only having missed two episodes since the start of the run in the U.S. Colin Mochrie is the only performer to have appeared in every episode of the U.S. version of the show.

Topics for the games are based on either audience suggestions or predetermined prompts from the host, who would set up a game and situation that the performers would improvise. The original host Drew Carey awarded arbitrary point values after each game, often citing a humorous reason for his decision. The points were purely decorative and served no practical purpose. He would reiterate this at the beginning of, and multiple times throughout, each episode by describing Whose Line as `` the show where everything 's made up and the points do n't matter ''. The style of the games were varied ( see Games, below ). Some featured all four performers, while others featured fewer. Between games, the performers sat in four chairs facing the audience. The performers who were not involved in a game remained in their seats. Additionally, the show was marked by humorous banter among the performers and host. At the conclusion of each episode, a winner or several winners were chosen arbitrarily by Carey. The `` prize '' was either to play a game with the host, or to sit out while the other performers did so. After this game during the first season of the series, credits simply rolled under the show 's theme. In the second season, the reading of the credits was performed by one or more cast members in a comedic fashion, based on a theme announced by Carey that often derived from a successful joke earlier in the show. The show 's `` short - form '' approach to improv received criticism from some improv actors. However, performer Colin Mochrie has stated the show was never intended to be the `` be-all and end - all '' of improv, but that it was meant to introduce improv to the masses. Performers / players Colin Mochrie, who joined the U.S. version after originally appearing on the UK version Like the UK original, the U.S. version of Whose Line Is It Anyway ? features four performers, two of whom, Colin Mochrie and Ryan Stiles, were regular, permanent performers throughout the original format, having featured prominently in the UK original ; Stiles since his first appearance in its second season in 1989, while Mochrie since his first appearance in the following season in 1991, with both making regular appearances in the UK version from 1995 until its end in 1999. Another performer who made frequent, recurring appearances was Wayne Brady, who appeared in the majority of episodes of the original format. During his tenure as host, Drew Carey also took part, though only in one game, after one of the performers was declared the `` winner '' and allowed to take his place at his desk in the studio ; host Aisha Tyler did not take part in games when the show was revived, but has occasionally joined in for a quick scene during the Scenes from a Hat game. As of 2017, Mochrie is the only performer to have appeared on every single episode of the American version. Alongside Mochrie and Stiles, other veterans of the UK series appeared on the U.S. version included Greg Proops, Brad Sherwood, and Chip Esten, with the show introducing several newcomers that took part, including Denny Siegel, Kathy Greenwood, Jeff Davis, Patrick Bristow, Stephen Colbert, Kathy Kinney, and Ian Gomez, though mainly in the early seasons of the show. Unlike the UK original, the US version occasionally featured a celebrity guest performer, such as Robin Williams, Kathy Griffin, and Whoopi Goldberg, while on other occasions, a celebrity made a guest appearance for individual games ; such appearance have included Sid Caesar, David Hasselhoff, Florence Henderson, Jerry Springer, Joanie `` Chyna '' Laurer, Richard Simmons, Katie Harman, Jayne Trcka, the Loyola Marymount University cheerleaders, Hugh Hefner, and Lassie. Celebrity guests became a regular feature of the show beginning with season 9. Improvisational musician Laura Hall, who appeared in the final season of the UK original, joined the original U.S. format for its entire run and performed piano and keyboards in games featuring improvisational singing by the cast members. From the second season onward, other musicians joined Hall -- Linda Taylor made frequent appearances playing guitar and occasionally keyboards, while Cece Worrall - Rubin, Anne King, Candy Girard, and Anna Wanselius appeared alongside Hall ( and sometimes also Taylor ) on occasion. Games The number and type of games played varied from episode to episode, yet while some games became more common over time, others faded from use. Some games are based on traditional improv games, with a considerable number brought over from the UK original, including Scenes from a Hat, Greatest Hits, Props, Hoedown, Helping Hands, Questions Only and Party Quirks. Others were new and uniquely created for both the U.S. original format, and the revived show, with several only receiving 1 or 2 playings due to them not having been well received by audiences.

All games were designed with the same principle of those from the UK original -- to test the performers ' improvisational comedy skills, with some games requiring the host to ask the studio audience for suggestions for specific topics or situations, while at other times these suggestions were written by the production staff, or submitted by the audience in advance, and chosen from among these. In addition, the host would control a buzzer which would signify the end of most games, or the end of individual sections of rapid - fire games such as `` Scenes from a Hat ''. In addition to being tested on their comedy skills in improv games, the performers are also tested on other skills, such as singing, dancing, or impressions, as Whose Line features a number of musical games, with one or more of the show 's resident musicians playing live backing music for them, except on a few occasions when pre-recorded music was also used. Although they had no bad feelings about these sort of games, many of the performers disliked them ; while Wayne Brady turned out to be well suited to them, having Chip Esten, Jeff Davis, Brad Sherwood and Gary Anthony Williams making frequent appearances as his duet partner, Stiles frequently expressed open disdain towards the `` Hoedown '' game, which became a bit of a running gag, while Mochrie rarely sings any lyrics, mainly preferring to deliver his lines in a spoken word fashion, much like in the UK original. History The title card of seasons 1 -- 8 of Whose Line Is It Anyway ? Whose Line Is It Anyway ? was created by Dan Patterson and Mark Leveson in 1988 as a radio show on BBC Radio 4 in the United Kingdom. This early incarnation of the show is notable as being the origin of its tradition of having the performers read the credits in an amusing style ; as it was a radio show, it was necessary for somebody to read the credits, and it was decided that it might as well be done as part of the program, rather than being done by a traditional BBC Radio announcer. This approach to reading credits was pioneered by the earlier BBC radio show I 'm Sorry, I 'll Read That Again. Indeed, the title of the show itself is a comedic riposte to another radio show, What 's My Line, merged with the title of a 1972 teleplay ( and eventual theatrical play ) Whose Life Is It Anyway ?. The radio series lasted for six episodes, after which Channel 4 developed the franchise for television. The British television version lasted for a total of 10 seasons, with 136 episodes, all of which were hosted by Clive Anderson. Colin Mochrie and Ryan Stiles, who would later star in the U.S. version, became regular cast members in the seventh and eighth seasons. The UK series was brought to the attention of Drew Carey, who worked with regular Whose Line ? performer Ryan Stiles, a co-star on The Drew Carey Show. Carey convinced ABC to air test episodes in the United States. The show turned into an inexpensive hit ( though less so than the British version ), and ABC kept Carey on as host. In its first season, the show aired on Wednesday nights at 9 : 30, right after The Drew Carey Show. It ranked 29th for the season, and averaged 13.1 million viewers per episode. The show ran on ABC for six seasons, benefiting from the low expectations of its Thursday night time slot, as ABC was not expected to mount a serious threat to what was then NBC 's longtime Thursday dominance in the Nielsen ratings. While the network would regularly premiere two new episodes in one night, there were several occurrences in which some episodes were skipped or postponed until a later date because of the airing of other new shows or specials. The format of the American version was very similar to the British program. A major difference was Carey 's use of the game - show facade, explicitly stating at the start of each episode that `` the points do n't matter, '' and sometimes emphasizing this throughout the episodes. The difference in standards in the UK compared to U.S. prime time meant stricter censoring of both language and content on the U.S. series. Production of the American version was canceled by ABC in 2003 because of low ratings, with already - produced episodes airing first - run into 2004. The ABC Family cable channel, which had been airing repeats of the show since 2002, also showed `` new '' episodes from 2005 to 2006, formed from previously filmed but unaired performances. Hiatus Following the cancellation, Drew Carey went on to create the short - lived Drew Carey 's Green Screen Show, which premiered in 2004 on the WB. The series was very similar to Whose Line ?, and featured many of the same cast. The major gimmick on that series was that the acting was done in front of a green screen, and animators later added cartoon imagery to the scenes. Carey and several cast members also started touring North America with a live - action show called ( Drew Carey 's ) Improv All - Stars. The show was a live stage show similar to Whose Line ?, and featuring many of the same games, though also with some new ones. The live shows started in 2003, and since 2006, are only seen on occasion, mostly due to Carey 's current television obligations. Colin Mochrie, Brad Sherwood and Drew Carey performed at the Just for Laughs festival in Montreal as `` Improv All - Stars '' in 2003 and 2004. Since 2005, Mochrie and Sherwood have toured semi-regularly as An Evening With Colin and Brad. The show was recorded on Stage 29 at Paramount Studios. Greg Proops and Ryan Stiles presented Stiles & Proops Unplanned which was a live improv comedy show based on the successful Baddiel and Skinner Unplanned format that took place at Centaur Theatre in Montreal, Canada in July 2008. They also tour with former co-star Jeff Davis under the name Whose Live Anyway ? doing live improv. Proops appeared as Max Madigan on Nickelodeon 's True Jackson, VP, and is currently hosting Head Games on The Science Channel and was the host of `` Odd News '' segments for Yahoo ! ( now called Broken News Daily ) while Esten has made multiple appearances in various TV series including The Office, ER ( also produced by Warner Bros. ) and Big Love and guest - starred in Enlightened. In 2007, Mochrie was host of a five - episode run of Are You Smarter Than a Canadian 5th Grader ? on Global TV in Canada. Carey, Stiles, Brady, and Esten were all later employed by American television network CBS ; Carey succeeded Bob Barker as the host of the long - running game show The Price Is Right ( after a short stint as host of another game show, Power of 10 ). In addition, Sherwood and Davis served as guest announcers for the 2010 - 11 season of The Price Is Right, after the departure of Rich Fields, who was eventually replaced by George Gray. Stiles appeared as a supporting character on the sitcom Two and a Half Men. Esten had a recurring role on The New Adventures of Old Christine and made a guest appearance in NCIS : Los Angeles, before moving to star in the ABC drama Nashville. Brady had a summer variety show on ABC in 2001, The Wayne Brady Show and then hosted a daytime talk show of the same name for two seasons, starting in September 2002. He also was the host of Fox 's Do n't Forget the Lyrics. In 2007, he made a guest appearance in one episode of 30 Rock, and has made several appearances on How I Met Your Mother as Barney Stinson 's homosexual brother. He also had a couple of guest appearances on Chappelle 's Show. Since October 5, 2009, Brady has been the host of CBS ' revival of the classic game show Let 's Make a Deal. Featuring Jonathan Mangum as announcer and Co-Host, this new iteration utilized some classic elements of improv from Whose Line, most notably Brady 's singing and comedic abilities, occasionally breaking out into spontaneous musical improv in front of or involving contestants, and not being a stipulated aspect of the particular game to be played. As of 2009, every main Whose Line participant has hosted at least one game show except Ryan Stiles. On November 18, 2010, Variety announced that Drew Carey would start a primetime improv show on GSN. The series, entitled Drew Carey 's Improv - A-Ganza, debuted on April 11, 2011 and featured most of the Whose Line regular cast before ending in June 2011 ; Rich Fields was the announcer for the series. A second season was not ordered and the show was terminated. On July 10, 2012, ABC premiered a new improv comedy series featuring several of the Whose Line alumni called Trust Us With Your Life. Some of the players included Colin Mochrie, Wayne Brady, Greg Proops, Jonathan Mangum, and Nicole Parker. However, on July 30, after only six episodes had aired, ABC pulled the remaining episodes after its host Fred Willard was arrested on a lewd - conduct charge at the Tiki Theater, an adult movie theater in Hollywood, California. In February 2013, Ryan Stiles revealed in an interview that he would be returning to Los Angeles in April for a new season of Whose Line, hosted by Aisha Tyler and featuring the original cast of the U.S. version. Colin Mochrie would later confirm the revival. CW revival Whose Line Is It Anyway ? returned to television, this time on The CW, with Colin Mochrie, Ryan Stiles, and Wayne Brady, and Aisha Tyler taking the role of the host. In addition to the traditional rotating fourth improv player ( often drawn from same pool of regulars that appeared on the original show ), a new feature was that of a `` special guest ''. This fifth player would not necessarily have an improv background, but would still participate in some of the improv games. The initial summer run was made up of twelve half - hour episodes with the three veteran players joined by a featured player, along with a different special guest for each episode who would play in some of the games. On July 29, 2013, The CW announced that it had renewed the show for a 24 - episode season, airing Fridays at 8 ET / PT starting March 21, 2014, due to solid ratings. Illness prevented Stiles from appearing in two season 10 episodes, the first Whose Line shows he had missed in nearly 20 years, dating back to the original British series. Frequent guest Greg Proops filled in for Stiles on these occasions. On July 18, 2014, The CW announced that the show will be returning for a 24 - episode eleventh season ( and third season on The CW ) which started airing on April 17, 2015. On August 11, 2015 the series was renewed for a twelfth season ( fourth on The CW ) to start airing May 23, 2016. On October 24, 2016 The CW renewed the show for a thirteenth season ( fifth season on The CW ) to start airing May 29, 2017. Performers Several of the performers, including the three regulars Brady, Mochrie and Stiles, had previously appeared in the original run of Whose Line in the UK ; other performers who had made appearances in the British version are Greg Proops, Brad Sherwood, Chip Esten, Karen Maruyama and Josie Lawrence, as well as musician Laura Hall. Mochrie and Stiles have been regulars since the show started, whilst Brady became a regular from season 2 - 7, appearing as a recurring performer in seasons 1 and 8. Mochrie is the only performer to have appeared in every episode of the US series of Whose Line ?, with Stiles having missed two recordings due to illness. The original host of the U.S. show was Drew Carey, who appeared in every episode of series 1 - 8. Carey notably took more of an active role in the show than his predecessor Clive Anderson, as following the announcement of the `` winner '' of each show, Carey would perform a game with the other performers. After the CW revival in 2013, Aisha Tyler took over as host, as Carey was the host of The Price is Right, which ran at the same time as Whose Line, however Carey is mentioned numerous times by Tyler and the other performers. Unlike Carey, Tyler does not perform full games with the other performers, however does occasionally interject in quick fire games such as Scenes from a Hat with her own suggestions.
