In February 2003, it was announced that Fox would start broadcasting on Cabovisão from March 1, one of the cable companies that existed at the time, as an exclusive channel to the platform.

Cristina Gomez, director-general of Cabovisão, explained to the Lusa news agency that the channel was "a unique experience in Portugal", combining "the greatest hits from the Fox studio, some Portuguese movies and the most important television series".

The primary target was defined as viewers in the 18-45 age range, with the aim of leading the entertainment segment in Portugal, similar to what happened in Latin America and Japan, despite the reduced coverage of Cabovisão, which had 17% of the share of the pay-TV operators at the time, against 80% from TV Cabo.

Portugal was a key market for the European expansion of the brand, primarily due to the fact that Portuguese viewers have long since been used to watch television series in their original soundtrack with subtitles.

[11] On November 2, 2006, the channel premiered Prison Break, when the network was available free for subscribers of the basic digital service of TV Cabo for two months.

[14] In the same year, a print advertisement promoting The Simpsons appeared in Angola depicting a localized version of the family, for the "premiere" of the series in the country.

[20] A similar campaign in was held in early 2011 for the premiere of Hawaii Five-0, involving an interpretation of the series' opening theme and Hawaiian dancers.

Fox set the date as National Hangover Day, and aired the first episode sideways on purpose, to target "hungover viewers".
