Yesterday's successful liftoff is believed to have sent China Central Television's advertising revenues soaring, with advertisers scrambling to secure rights to slots during the exclusive broadcast. The state-run station is understood to have sold all the advertising space on four of its channels by Tuesday. A source in the CCTV advertising department confirmed the slots were worth at least 65 million yuan. 'We had planned to sell slots worth 65-70 million yuan in total for the broadcast by now and the goal was met,' the source said. The coverage is seen within CCTV as being of a highly sensitive nature and a 'duty of political importance'. 'No details regarding the advertising can be disclosed. You can just watch our broadcast to count the enterprises that have paid for advertisements,' the source said. According to National Business Daily, five seconds of air time on CCTV was available for 1.46 million yuan, 15 seconds for 2.66 million yuan and 30 seconds for 5.32 million yuan. The report said advertisers who wanted to ensure that commercials for competing products were not aired could pay two or three times the regular rate. Viewers watching the mission coverage yesterday would have seen commercials for more than 10 products, including DaYang Motorcycles, Monarch lubricant, Nissinhualong Food's Jinye instant noodle and medicines. But an advertising agent working with CCTV said it would be difficult to calculate how much the broadcaster made as advertising revenue did not directly translate into profit. 'Unlike the Shenzhou V voyage which only lasted for hours, the Shenzhou VI is lasting for five days, so the total 65 million yuan is divided over many days,' the agent said. 'It's hard to count how profitable the live broadcast will finally be, but it surely will be profitable. 'CCTV is reluctant to reveal its ad sales as it doesn't want to attract unnecessary public criticism about its exclusive broadcast rights.' Critics allege that CCTV makes too much money from its privileged monopoly of coverage of important events. The station announced at the end of September that its advertising sales for 2006 could exceed 2005's 5.2 billion yuan.
