Portal is a former 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 skit comedy show, and a news show. As a whole, Portal was an attempt at a new type of show by blending satire, unique stylistic elements, and various levels of dramatism.

Portal was the first television series to use machinima.

Dave Meinstein, the host of the show, never completely introduces us to the purpose of the show. He is introduced as the "host cybernaut" of The Hub, a somewhat rusty complex through which all worlds - virtual and real - are linked. Along with his computer, VAL, it is presumed that his job is to watch over this Hub and to protect the known universes from any danger that may arise. Occasionally interspersed with skit comedy and news, the show takes on its true focus after a few episodes.

Dave's first major problem - and the inciting event for the storyline - is an attack by an unknown force named The Ultimate. The Ultimate is not known as anything but a nebulous force of evil for most of the show.

Portal may refer to:

Television (TV) is a telecommunication medium for transmitting and receiving moving images that can be monochrome (black-and-white) or colored, with or without accompanying sound. "Television" may also refer specifically to a television set, television programming, or television transmission.

The etymology of the word has a mixed Latin and Greek origin, meaning "far sight": Greek tele (τῆλε), far, and Latin visio, sight (from video, vis- to see, or to view in the first person).

Commercially available since the late 1920s, the television set has become commonplace in homes, businesses and institutions, particularly as a vehicle for advertising, a source of entertainment, and news. Since the 1970s the availability of video cassettes, laserdiscs, DVDs and now Blu-ray Discs, have resulted in the television set frequently being used for viewing recorded as well as broadcast material. In recent years Internet television has seen the rise of television available via the Internet, e.g. iPlayer and Hulu.
