As Scott says, it was always going to be hard to replace the Big Breakfast, even if the audience for that show had slumped in recent years from a high of 1.5 million. Ri:se, unlike the Big Breakfast, airs 52 weeks a year without a break - a serious amount of live TV for any organisation to turn out. But the show is disproportionately important to C4, which has to deliver high numbers of elusive 16 to 34-year-old viewers to advertisers to make most of its living. Shows such as Ri:se and the Big Breakfast are meant to "punch above their weight", in the words of one competitor, because while they may not draw huge numbers of viewers, they can create "profile", just as the likes of Johnny Vaughan and Denise Van Outen make for good celebrity publicity. C4, like the other commercial channels in the UK, needs every advertising pound it can get this year, as the industry comes out of a deep recession.
