Although these public attacks led to reports of concern in Channel 4 management, postponement of Wank Week did not take place until early February 2007, only a month before its planned screening. There had been a major racism controversy during January's "Celebrity Big Brother" contest, and the launch of Wank Week raised the prospect of further embarrassment at a critical time: Ofcom was reviewing the channel's finances ahead of the digital switchover, with the continued nature of Channel 4's existence as a state-owned but advertisement-funded public service broadcaster at stake. "Broadcast" magazine reported that several senior figures at Channel 4 had felt uncomfortable about Wank Week, including deputy chairman David Puttnam and chairman Luke Johnson, although they had originally not intended to formally object. The atmosphere following the "Celebrity Big Brother" racism row was suggested to have influenced the decision.
