Richard Desmond's Channel 5 has been censured by Ofcom for airing "excessively noisy" sponsorship credits for Sony's PlayStation 3 console around Five Movies.
Sony Computer Entertainment agreed a 12-month deal in January with Channel 5 for the PS3 brand to appear alongside primetime movies on Channel 5, 5* and Five USA.
Media regulator Ofcom received 17 complaints about the loudness of the sponsorship credits broadcast around Five Movies between February 3 and March 15.
After conducting technical assessment of the credits, Ofcom found them to be "excessively noisy" and in breach of guidelines that credits should not be louder than any programming on the channel.
Channel 5 said that the technical assessment of all its sponsorship credits, channel promotions and commercials is outsourced to a third-party company, which failed to carry out the appropriate subjective loudness test due to "human error".
