OFCOM, Britain's TV watchdog, has warned broadcasters about showing "sexualized clothing and dance routines" before the 9 00 p.m. watershed hour, when children are likely to be watching. "It is important to note that in pre-watershed content, OFCOM would not expect to see singers and dancers wearing clothing that does not adequately cover their bodies (in particular their breasts, genital area and buttocks)," it warned. Moreover, it said, "particular caution" should be exercised in the case of family shows that begin earlier in the evening but continue after 9 00 p.m. In particular, it cited the season finale of last year's The X Factor , which featured a sexy dance number by Christina Aguilera that OFCOm suggested was "unsuitable for children or close to the limits of acceptability."
