Seven years’ free marketing counseling – that is what Mayor Bloomberg and a deputy mayor, Daniel Doctoroff, offered more than two dozen international sports federations during a presentation at Berlin yesterday aimed at bringing the 2012 Olympic Games to New York City.

“We’re looking forward to making a presentation about what New York can do to promote the 28 different sports that are represented here,” Mr. Bloomberg told reporters in the German capital. “There is no better city to build a brand than New York.”

With 80 days to go before the International Olympic Committee votes on which of five cities – New York, London, Madrid, Moscow, and Paris – to name as host of the Games, New York’s 2012 team is trying to exploit its city’s reputation for marketing know-how to land the Games.

The mayor and Mr. Doctoroff unveiled a program, called the Olympics Sports Development Partnerships, during one of a handful of occasions when would-be host cities are allowed to lobby members of the IOC directly. As envisioned, the partnerships will allow each Olympic sport to use the seven years leading up to the Olympic and Paralympic Games of 2012 to generate a marketing program to woo a whole new crop of fans to their sport.

New York offered to give each of the 28 Olympic sports federations a team to help develop a long-term plan to expand the sport’s presence and support in America. It would create a Sports Marketing Council, led by the commissioner of the National Basketball Association, David Stern, and it would provide comprehensive marketing advice and assistance in the seven years leading up to the Games – all free of charge.

The plan also would try to beef up interest in individual sports on a grass roots level by expanding youth sports programs in the city, developing national clubs, and working with universities to bring athletes in for training. New York would also try to become host of national and international competitions to build an audience for various sports featured at the Summer Games. The idea is to capitalize on New York’s strengths – from press exposure to international communities – to drum up new fans for sports that might not have a natural audience in America.

“We will use the seven years before the Games to work with every Olympic Sports Federation to strengthen each sport and bring it to a new level of visibility, participation, and fans in New York and throughout the country by opening of the Games,” Mr. Bloomberg said in Berlin.

Paris, Madrid, and Moscow made less direct pitches as the final five vying for the 2012 Games presented their bids to the 28 international federations in Berlin. The presentation is a key one for New York, which was seen as lagging behind Paris and London in the Olympics stakes. The Berlin session is the last major opportunity to make a pitch to IOC members before a meeting at Singapore in early July at which the 2012 host city is to be chosen.

New York and London were the only cities to announce major new initiatives, targeting their plans specifically to the federation officials who run the Olympic sports. Most federation chiefs are also IOC members eligible to vote in Singapore.

Mr. Bloomberg also used the opportunity to remind IOC members just how much progress New York City has made since the September 11, 2001, terrorist attacks.

“This is the perfect moment for the city to embrace sports,” the mayor said. “Four years ago our city was shaken, but New Yorkers today are more determined than ever. We know nothing can help us achieve this more powerfully than sport.”

An American who is president of the archery federation and a vice president of the IOC, Jim Easton, said the New York proposal to the federations would impress Olympic officials.

“It’s a great idea to be able to promote the sports seven years in advance – that’s a real legacy,” Mr. Easton told the Associated Press. “I think the New York [presentation] had a big impact. That was different from what they’ve heard in the past. For this group, that will resonate with them.”

London, for its part, promised that BBC television would provide special Olympics sports and highlight coverage in the run-up to the Games. The British Olympics organizers basically would finance the housing and living expenses of a technical delegate from each federation for up to a year so that the delegates could oversee preparations for the Games. Hotels in London set aside 40,000 rooms with guaranteed rates and federation officials won’t be bound by any minimum stay requirements, the AP reported. London also announced confirmation that a new field-hockey venue would be built in the proposed Olympic park, regardless of whether the city gets the Games. Mayor Ken Livingstone said only two permanent venues remain to be built.

Paris, which has been considered the front-runner from the outset, didn’t offer any new proposals.

Madrid took to the Berlin sessions Juan Antonio Samaranch Jr., son of the former IOC president.

Moscow’s mayor, Yuri Luzhkov, promised that all facilities would be completed two years before the games. Sixty-five percent of the venues already exist, from the 1980 Moscow Olympics.
