NBCU may break a record of its own with the Summer Olympics next month, set as it is to pull in more than $1 billion in ad revenue for the summer games, reports MediaBuyerPlanner.

NBC rakes in $750,000 per :30 spot for broadcast coverage, 85 percent of which is already sold. That's a CPM of 10 percent higher than for the 2004 Olympics, writes The Hollywood Reporter. The $1 billion — assuming that number is reached — includes NBC’s cable networks (USA, MSNBC, CNBC, Oxygen, Telemundo) and NBCU's online ad inventory.

Strong ad categories include auto, telecom, soft drinks, movies and retailers offering back-to-school sales, while strong Olympics categories include swimming and gymnastics.

NBCU claims that it will broadcast more Olympics hours on its networks and websites than the combined amount of coverage for every previously televised Summer Games, Reuters reports.

Last week, NBC unveiled the Total Audience Measurement Index (TAMI), which will offer daily audience measurement data during its 17 days of Summer Olympics coverage.

The data will include daily TV ratings from Nielsen along with data about online and video-on-demand from Quantcast, and measurement of mobile audiences. TAMI data will be available for the previous day and night’s coverage the next day at 6 p.m.

On Monday NBC posted a rise in revenues of 7 percent and net profit of just 1 percent in the second quarter.
