BEIJING, Oct. 23 (Xinhua) -- The Olympic Games are not getting over-commercialized, chief of the International Olympic Committee said on Monday.

"I would be very surprised by what people say (about over-commercialization) because ... if you look at the Olympic Games, you will not see advertising and billboards in the stadium like what you would see in all other major sports competitions," said Jacques Rogge.

"And, we are the only major sports competition where there is no prize money for the athletes," he added.

Rogge's remarks came after some people voiced concerns about the over-commercialization of the Olympic Games as the Beijing 2008 Games has enlisted dozens of sponsors and is expected to make an unprecedented profit.

"If the IOC would not get the support of the commercial world and the television rights, then we could not afford to spend money in developing countries like what we are doing now," said Rogge.

Around 94 per cent of the revenues from the IOC's marketing program is used to assist developing countries and the organizing committee of each Olympic Games, said Rogge.

"We will be paying an excess of 1 billion US dollars to BOCOG. That is the support of IOC to BOCOG," he said.

Rogge admitted that important as the Olympic marketing programsare, commercial interests should not manipulate sports.

"We are taking care of that," he said.
