NBC is set to "break even" on its Olympics coverage, rather than lose money as previously expected, the head of NBCUniversal said Wednesday. The company had expected at one point to take a $200 million loss on the London Olympics. NBC paid $1.2 billion for the rights to show the games on TV and online in the U.S. It has said that it sold more than $1 billion in ads, breaking the record of $850 million set during the Beijing Olympics in 2008.
