Portal is a TV show that aired on G4. During its two-season run from 2002–2004, it was one of the most popular shows on the network. Written, produced, and hosted by Dave Meinstein, Portal was in many ways a comedy, a soap opera, a sketch comedy show, and a news show. It was an attempt at a new type of show by blending satire, stylistic elements, and various levels of dramatism. Portal was the first television series to use machinima.
On June 22, 2006, Meinstein announced at his message board that Portal would be returning to G4 as webisodes on g4tv.com. However, due to reported computer problems, the project was delayed, and nothing has been mentioned since. Portal was included in the G4 Rewind block in the summer of 2008.
