In this Friday, July 27, 2012 photo fireworks explode during the Opening Ceremony at the 2012 Summer Olympics, in London. The International Olympic Committee expects that almost 900 million people watched part of the London Games opening ceremony on television. The IOC's television and marketing director Timo Lumme says it is the target figure for "global viewership ... that's all eyeballs across the world." The final, official rating will be lower than 900 million. It counts in-home viewers watching for longer periods and will be announced within months. Lumme says around 80 of 200 national television markets have audited figures. Others are estimated. (AP Photo/Paul Sancya)
