Politicians, celebrities and fans cheered the parade of all the athletes from the 204 nations that will participate in the games. First Lady Michelle Obama and presidential candidate Mitt Romeny were also amongst the crowd.

The amazing $42.5 million opening ceremony was been prepared by Oscar- winning director Danny Boyle, and will mark the opening of the two week sports fest. NBC will have 2,000 more hours of coverage of the London games than of the Beijing games.

BBC and Youtube will stream live coverage and The International Olympic Committee (IOC) will be posting videos directly on Youtube from the Games.

The $42.5 million ceremony was described by Boyle who said "We hope the feeling of the show is a celebration of generosity. I don't think it's eccentric, but I wouldn't because I'm British, but other people might think it is."

Fans waited outside for as early as eight hours before the start of the show, according to Bloomberg news.
