Almost every person on the planet with access to a television will watch the Sydney Olympics at some stage during the month, officials said yesterday.

International Olympic Committee (IOC) marketing commission chief Dick Pound said the Games, which open on Friday, would be the largest Olympic telecast ever, with an estimated total global television audience of 3.7 billion people.

The IOC estimates there are 3.9 billion people in the world with access to television. The Games will be broadcast in 220 countries.

"That is an increase of 700 million over 1996 (at the Atlanta Games)," said Pound who, despite the biggest bribery scandal in the IOC's history over the last two years, was able to present a glowing report on the IOC's marketing programmes to members at a meeting before the Games.

The IOC has been struggling to boost its image ever since the Salt Lake City 2002 Winter Games scandal.

Despite the IOC's severe image problems, the cash tills keep ringing. Sponsors are still signing up to back the Games, although they now have a "morals" opt-out clause allowing them to walk away from the IOC if it goes off the rails.

Pound said the television rights fees for Sydney totalled $1.331 billion compared to $895 million in Atlanta.

Some $798 million will go to Sydney organisers with $533 million distributed between national Olympic committees, international sporting federations, the IOC and Olympic programmes like the new world anti-doping agency.

Nine of the 11 leading Olympic sponsors have renewed their contracts and another one is expected to announce an agreement before the opening ceremony, he said.

Asked if recent critical press coverage had worried the sponsors just before the Games, marketing director Michael Payne said: "We're getting strong reviews from the sponsors, focusing on the Games and the athletes, not on the IOC."

Sydney has had its controversies with ticket rows, but the city is set to boast the most successful sponsorship programme, with revenues of $626 million.

"Eighty per cent of the total tickets have been sold," Pound said. "The highest ever was 82.3 per cent, so it shows every sign of being an Olympic record."

The IOC estimated that 35 million people would look at the Games via the internet, compared to two million for the Nagano Winter Games two years ago.

The IOC has also managed to arrange a television signal for troubled East Timor, which has sent a small team to the Games following its vote a year ago to end 23 years of Indonesian rule.
