Carsey-Werner Productions (in some incarnations, Carsey-Werner-Mandabach Productions) is an independent production company founded in 1981 by former ABC writer/producer duo Marcy Carsey and Tom Werner (now co-owner of the Boston Red Sox baseball franchise). Caryn Mandabach was made a partner in the firm in 2001 (she joined in 1984), but left in 2004 to embark on her own production deal.
Carsey-Werner has had its own production and distribution facilities since the mid/late 1990s. Prior to controlling their own distribution, Viacom Enterprises, and later Paramount Domestic Television, syndicated their programming for them. In 2002 they announced a deal with Paramount Pictures to develop feature films through the studio.
As of February 22, 2007, Carsey-Werner has begun removing videos off YouTube regarding That '70s Show with the copyright claim being the only explanation; it is unknown if other Carsey-Werner series were affected. Carsey-Werner now has its own YouTube channel.
