Olympics is not only a mega sporting event, it is also a great revenue generator for the host country.
It is estimated that between 2005 and 2008 the event has generated $5.5 billion worth revenue through broadcasting, licensing, ticketing, domestic sponsorship and the main event.
Of these, broadcasting is the major contributor to the kitty. More than 200 countries will receive live broadcasts of the 2012 London Olympics. Broadcasting revenues have risen steadily since 1960 and this year it is expected to be $3914 million.
Domestic sponsorship covers the local markets and is managed by the organizing committee of the host nation. Top Program covers long term multinational corporations and is managed by the Olympic committee.
Ticketing revenue is directly proportional to the buying power of the host citizens. Licensing revenue is the least of the five contributors of Olympic revenue.
