Nielsen Finalizes Telephia Purchase

Nielsen Co. completed its acquisition of San Francisco-based Telephia, which provides syndicated consumer research to the telecom and mobile media markets, officials said Friday.

The acquisition is part of Nielsen’s strategy of providing clients with measurement and analysis of consumer behavior and media use across all platforms.

Sid Gorham will continue to serve as Telephia’s president and CEO, reporting to Nielsen executive vice president Susan Whiting.

Nielsen Wireless, the company’s recently launched service to measure consumer usage of mobile Internet, mobile video and other related content services, will be integrated into Telephia, whose headquarters will remain in San Francisco.

Telephia currently serves more than 100 clients in the United States, Canada and Europe from all sectors of the telecom and mobile media markets, including mobile operators, device manufacturers, retailers, infrastructure vendors, investment analysts and content providers.

The company provides independent, technology-based measurement of consumer behavior, product quality and consumer attitudes. It also provides the mobile industry’s standard for subscriber market share, network quality, consumer satisfaction and mobile media consumption.
