TechTV was a 24-hour cable and satellite channel based in San Francisco featuring news and shows about computers, technology, and the Internet. In 2004, it merged with the G4 gaming channel which ultimately dissolved TechTV programming. At the height of its six year run, TechTV was broadcast in 70 countries, reached 43 million households, and claimed 1.9 million unique visitors monthly to its website. A focus on personality-driven product reviews and technical support made it a cultural hub for technology information worldwide, still existing today online through its former hosts' webcasts, most notably the TWiT Network and Revision3.

It originally was called ZDTV by its founder, Ziff-Davis, when it debuted on May 11, 1998. It later was owned by Paul Allen's Vulcan Ventures. Vulcan Ventures sold TechTV to G4 Media (owned primarily by Comcast), which merged it with the video game channel G4 in May 2004 to form G4techTV. In February 2005, the name was changed back to G4, eliminating TechTV from the name completely.

He is currently a managing editor at Revision3 where he hosts Tekzilla and formerly HD Nation and Systm.

On March 25, 2004, Comcast's G4 gaming channel announced a merger with TechTV. This move became hugely controversial among loyal fans of TechTV. Around May 6, G4 announced the termination of 250 employees from the San Francisco office by July 10, 2004, allowing approximately 80 to 100 employees to transition to G4's main office in Los Angeles, California if they agreed to relocate there. Norton chose to stay in San Francisco instead of moving to Los Angeles, and left the company.
