Variety is reporting rumours that CBS is to renew Two and a Half Men for 3 more seasons, taking the show into its 9th season in 2011/2012.
The Big Bang Theory is thought to be renewed for two additional seasons, taking it through to its fourth season in 2010/11.
Both shows were created by Chuck Lorre, who serves as executive producer on both. Warner Bros. Television produce the shows, making this a major deal for them.
