ITV

ITV was a broadcasting company active since the 20th century. The programs broadcast included the television series Armchair Theatre (PROSE: The Taint, The Ancestor Cell) and The Cook Report. (PROSE: The Dying Days)

During the first attempt in the 1970s by the Nestene Consciousness to invade Earth, ITV, along with BBC, issued warnings for the public to stay inside, and this saved many lives. (PROSE: Doctor Who and the Auton Invasion)

An ITV reporter was present at the Silurian conference. (AUDIO: The Coup)

The Tenth Doctor, when addressing his human companion, told them not to use the TV remote control, which was recently disconnected from the sonic screwdriver, to switch over to ITV, lest the galaxy implode. (GAME: Attack of the Graske)

In the 2000s, Kathy Nightingale and Sally Sparrow discussed their own series of adventures, to be called "Sparrow and Nightingale", and suggested it air on ITV. (TV: Blink)

When the Eleventh Doctor saved Albert Hall from being blown up, one of the side effects noted was that ITV went off air. (TV: Doctor Who Scene)

In response to the BBC series Surrender, Earthlings!, ITV tried to make their own rival sci-fi series, Invasion of Earth, but this did so poorly it nearly bankrupted the network. (PROSE: Not So Much a Programme, More a Way of Life)

Alternate timelines
In an alternate universe, ITV1 aired the series, Detects Factor, hosted by Sherlock Holmes. (PROSE: Just a Minute...)

Behind the scenes
ITV airs Coronation Street, Emmerdale, and The Chase. It formerly aired Trisha Goddard.

It also aired Thunderbirds in the 1960s. Though not a Doctor Who spin-off, the series was established by the contemporary tie-in comics in TV Century 21 to take place in the same universe as The Daleks, and thus, by association, Doctor Who itself. This was directly shown in one TV episode of Thunderbirds, The Man from MI.5, where a report about the Dalek invasion of Solturis (as seen in The Penta Ray Factor) was seen among the papers of a 2060s British Secret Service member. This ironically means that the first licensed appearance of the image of a Dalek on TV outside Doctor Who occurred not on the BBC but on its rival channel ITV.

The Doctor himself has appeared in an ITV-exclusive piece of content only once, when the Seventh Doctor made an in-character appearance as the Seventh Doctor on The Disney Club on 23 January 1994. The show aired on GMTV, an ITV subsidiary.

Since 2022, the video on demand service is a part of 's premium service in the United Kingdom.
