Sega TV was a prodominantly European advertising campaign used by Sega during the early 1990s. It was a mock pirate television station, which among showing bizarre films and shows frequently advertised the Sega Mega Drive, Sega Mega-CD and Sega 32X. It is considered by many to have been quite a successful campaign, being the European equivalent of Segata Sanshiro or the Sega Scream. Sega TV should not be confused with Sega Channel, a real television channel promoted by Sega.
Sega TV claimed to be the first "interactive channel", and was generally meant to be loud and abnoxious to counteract Nintendo's quite pedestrian marketing campaign in this region. It is possible that it was inspired by the 1987 Max Headroom broadcast signal intrusion, perhaps the most famous attempt at hijacking a television channel for a short period of time.
Sega TV's "mascot" was the "Sega Pirate", who was seen in many television advertisements, as well as in European promotional videos and occasionally in magazines. There was a limited edition Sega Game Gear bundle with Sega Pirate branding, and it appears on the cover of Sega Ages: Volume 1 for the Sega Saturn.
Both the Sega TV and the Sega Pirate were axed when the company's focus shifted to the Sega Saturn.
Sonic the Comic included "Pirate S.T.C." comics strips, based off Sega TV. The single story arc was running from issue #28 to issue #33. It was one of the only comic strips not based off videogame in Sonic the Comic, another one being about Megadroid, the mascot of the Comic.
(one day Sega Retro should probably host the whole set)
