Short Answer: 3.
Long Answer: We started the show only interviewing Webcomic creators and called the show TGT Webcomics (Two Guys Talking Webcomics).
A few years later, the show changed to TGT Media (based on the company Kurt Sasso created for multimedia film projects).
Finally the show settled on: Two Geeks Talking and shouldn't change anytime soon.
Although, TGT itself has changed a few times from: Two Guys Talking to Two Geeks Talking. But, the mnemonic TGT has remained.
