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.

The merger caused one of TechTV's most prominent personalities, Leo Laporte, to leave the channel because of a contract dispute.

The Canadian produced version of the show was briefly aired in the United States from August 2005 to January 2006, though individual episodes could have been purchased through Google Video in the U.S. On November 11, 2004, G4techTV announced that many of its employees, including Alex Albrecht and Yoshi DeHerrera, were terminated.

G4techTV also announced the cancellation of its popular late night variety show, Unscrewed with Martin Sargent, along with its weekly news program Pulse.
