Four adult television channels have been taken off the air for showing "sexually explicit" material.
Communications regulator Ofcom has revoked the licences of Tease Me, Tease Me TV and Tease Me 2 and 3 for "serious and repeated breaches of the Broadcasting Code".
Viewers of the channels, which promote adult chat lines, were encouraged to call the female presenters on premium rate telephone lines.
An Ofcom spokesman said: "Over a sustained period of time the licensees have transmitted content that was too sexually explicit for the time of day or being broadcast unencrypted.
"Some of the material broadcast was so strong that it would be considered equivalent to BBFC R18 rated material. This is not permitted on British TV - either free-to-air or under encryption."
The two companies, Bang Channels Limited and Bang Media (London) Limited, which run the channels, were fined £157,250 in July for breaching the Broadcasting Code.
