G4techTV was a cable and satellite channel resulting from a merger between Comcast-owned G4 and TechTV. The headquarters was in Los Angeles. The name changed back to G4 on February 15, 2005, in the United States.
On March 25, 2004, Comcast announced its plans to purchase TechTV, a channel devoted to computers and technology. The purchase was completed on May 10, 2004, allowing Comcast to merge their G4 station with the newly acquired TechTV, resulting in G4techTV. G4techTV officially launched in the United States on May 28, 2004.
G4techTV kept shows from TechTV, such as The Screen Savers, as well as shows previously on G4, such as The Electric Playground. The merger caused one of TechTV's most prominent personalities, Leo Laporte, to leave the channel because of a contract dispute. Laporte had been the host of Call for Help, a call-in help show, which was cut after the merger. A new Call for Help series hosted by Leo Laporte began airing on G4techTV Canada (now called G4 Canada), the Canadian affiliate of G4techTV, on August 16, 2004; the series ended on February 26, 2007. The Lab with Leo Laporte replaced Call for Help in April 2007 before ending in August 2008. The Canadian produced version of the show was briefly aired in the U.S., but this ended on January 3, 2006, though individual episodes could have been purchased through Google Video in the US.
G4 is a Canadian English language Category A specialty channel owned by Rogers Media. The name is licensed from NBCUniversal, whose parent company formerly owned a minority stake in the channel. Originally based on the U.S cable network, TechTV, G4 is a lifestyle channel that broadcasts programming related to technology.
On November 24, 2000, through a joint venture, Rogers Media (33.34%), Shaw Communications (33.33%) and TechTV US (33.33%) were granted approval by the Canadian Radio-television and Telecommunications Commission (CRTC) to launch a Canadian version of the U.S. television channel TechTV, described by its nature of service as "providing programming about computing, technology and the Internet." The channel launched on September 7, 2001 as the Canadian version of TechTV.
After months of speculation, on March 25, 2004, Comcast announced it would acquire TechTV from Vulcan Programming Inc., with plans to merge TechTV with its own gaming-related channel, G4. As part of the purchase, Comcast acquired TechTV's 33.33% interest in the Canadian version, spinning it off into its subsidiary, G4 Media. The transaction was completed on May 10, and the American services were merged into G4techTV on May 28, 2004. TechTV Canada would follow suit and be renamed G4techTV on the same date. On February 15, 2005, less than a year after the merger, the American version was renamed back to G4. In June of 2006, Shaw Communications sold its interest in the channel to the managing partner, Rogers Media. At an unknown date, Comcast also sold its interest to Rogers, giving it full ownership.
