Celebrity Big Brother, the British reality TV show which was at the centre of controversy over the alleged racist bullying of actress Shilpa Shetty in January, is to be scrapped, media reported today.Channel 4 will turn its back on the reality show, which attracted 54,000 complaints and sparked international outrage over the treatment meted out to Shilpa by her fellow participants, and four other successful programmes as it aims to concentrate on new, high-quality material, the Daily Mail tabloid said.However, industry insiders believe the decision not to run the celebrity show in 2008 may herald the beginning of the end of Big Brother.Ratings for the current non-celebrity series are down on last year. And Channel 4 admitted that the summer version could be moved from Channel 4 to the smaller digital channel E4 in future.(Reporting by H S Rao)
