LONDON (Reuters) - British media regulator Ofcom has fined Playboy TV 22,500 pounds ($32,990) for airing sexually explicit images in breach of broadcasting rules.

It said on Thursday the free-to-air channel Playboy One had broadcast unencrypted raunchy, and what the watchdog deemed offensive, material until September 2008.

Ofcom had received five complaints relating to seven late night programs broadcast between September and December 2007.

Shows investigated included: “Sexy Girls Next Door,” “Sexy Urban Legends” and “Adult Stars Close-up.”

“Depending on the individual breach, the explicitness, strength and, or, sustained nature of the sexual content and language was unacceptable for broadcast on an unencrypted free-to-air channel,” Ofcom ruled.

It said Playboy TV UK/Benelux Ltd had failed to ensure adequate protection for viewers from “potentially harmful or offensive material.”
