With more than 400 clean-tech infrastructure projects in and around Beijing, General Electric Co (GE), a global Olympic Sponsor, played a major role in ensuring that the Games were truly a "Green Olympics".

These projects have already generated more than $700 million in revenue, $200 million more than the firm initially expected.

In addition, during its coverage of the Beijing Games, NBC Universal, in which GE is the major shareholder, raised more than $1 billion in advertising revenue.
