The overnight ratings for New Year's Day have been delayed. The panel used to compile the figures was changed on 1st January. The new system from BARB has been in preparation for four years and has been run in parallel with the old system since April 2009. It was expected to seamlessly launch with the figures for 1st January 2010, however there has been an unexpected delay. The overnight figures for Doctor Who will appear on the news page as soon as they become available.
