As the countdown to the London Olympics 2012 opening ceremony draws closer, search giant Google celebrated the occasion with a doodle on its home page, sporting five athletes, incidentally appearing to signify the five Olympic rings.

The £27m opening ceremony of Olympics 2012, fashioned as a three-hour extravaganza and directed by award-winning director Danny Boyle, is expected to be watched by a global audience of over one billion with 60,000 from the main stadium.

Olympics 2012 will be declared open by Queen Elizabeth II and Prince Philip, the Duke of Edinburgh. The spell-binding ceremony is said to feature world icons, including Sir Paul McCartney, David Beckham, actor Daniel Craig and the U.S. First Lady Michelle Obama.

The Social Media is already abuzz with messages greeting the mega event. In celebration of sportsmanship, Twitter has already hosted a special page in association with NBC that brings together sportstars, their families and fans on a common platform. This move assumes significance as Twitter turns the official narrator of the mega-sporting event, compiling and corralling tweets from all stakeholders.

The Twitter special page already follows 1,287 athletes and has attracted 1,152,401 followers in a very short period.

Kristie Kenney, the current U.S. Ambassador to Thailand, tweeted: It's almost Olympic time! For first time, @USOlympic has more female team members than male. #girlpower."

Facebook has also hosted a special page that boasts of 3,028,990 likes, with 137,559 people talking about it.

The digital, electronic and print media is also eagerly watching the London Olympics 2012 Opening Ceremony that is expected to commence at 20:00 GMT. London earns the unique distinction of being the only modern city to host the games three times, with the first two being held in 1908 and 1948.
