CBS Gets Creative
With Mobile Ad
Consortium

NEW YORK, NY/8/2/07–CBS Mobile has forged partnerships with four of the country’s leading mobile advertising-enabling companies – AdMob, Millennial Media, Rhythm NewMedia and Third Screen Media, in an effort to build a full-service approach to mobile advertising for its entertainment, news and sports programming. In line with its focus on innovation, industry firsts and open and non-exclusive partnerships with cutting-edge companies, CBS Mobile is the first major broadcast network to work with AdMob, Millennial Media and Rhythm NewMedia.

Two of the four–Third Screen and AdMob–work closely with the publishing industry. CBS also owns Simon & Schuster, one of America’s largest publishing houses.

“We believe mobile advertising is one the biggest business opportunities in the mobile world, and we want to be at the forefront of it,” said Cyriac Roeding, Executive Vice President, CBS Mobile. “Teaming up with best-in-breed companies in an open and non-exclusive way is the cornerstone of our strategy – and these companies are leading the mobile advertising marketplace in terms of intelligent ad serving and distribution technologies and services. They will enable us to expand our relationship with our Top 200 advertisers while reaching thousands of smaller advertising brands from around the world wanting to place ads around CBS Mobile content.”

CBS also announced that starting immediately, it will provide clients with one of the widest menus of mobile advertising options in the market, ranging from text and banner ads on mobile websites, to commercials in video news and sports alerts, to video ads within mobile video, to commercials on CBS Mobile’s 24/7 television network.

The four companies offer varying areas of expertise in mobile advertising.

AdMob is a leading mobile advertising marketplace. AdMob serves over 1 billion ads per month worldwide and over 350 Million per month in the US alone. AdMob serves banner and text ads on mobile web pages for advertisers and their agencies.

“CBS has consistently provided great content and innovative features to its users,” said Omar Hamoui, AdMob CEO. “AdMob is proud that CBS has chosen the AdMob Marketplace to serve and manage its mobile ads based on our scale and advertiser base.
