CMGI To Increase Ownership Stake in Magnitude Network.

ANDOVER, Mass.--(BUSINESS WIRE)--Jan. 4, 1999--

Provider of Internet Radio Solutions Becomes Newest

Majority-Owned Addition to CMGI Internet Group

CMGI, Inc. (NASDAQ:CMGI) today announced that it will exercise its option and increase its ownership stake to 88% of Magnitude Network, a leading provider of Internet solutions for radio broadcasters. The formal close of the purchase is expected to be completed in late January.

Magnitude Network provides broadcast organizations with a fully-functional Internet presence that complements their on-air service and personality to

increase listenership, adds value for advertisers, and creates new revenue sources. Its Rad-Net technology provides a unique station presence on the Web with a variety of sophisticated functions, including broadcast-quality, stereo Web-casting. Rad-Net also provides a new dimension of impact for broadcast advertisers and product merchandisers, as well as powerful audit capabilities that give advertisers the critical, up-to-date listener/viewer data needed to evaluate their messages and product offerings.

CMGI completed its initial investment in Magnitude Network, totaling 19.9% of the company's fully diluted equity, in July 1998. Since then, Magnitude Network has reached a number of significant milestones in its goal to become the leading provider of Internet radio services and solutions, including:

-- A market-leading partnership with Arbitron and fellow-CMGI affiliate Engage Technologies to develop audience ratings services for Internet audio and video;

-- The "Live Radio" Channel on RealNetwork's newly released G2/Real Player; as well as

-- A growing network of radio station affiliates, now totaling nearly 200 stations nationwide

"Our initial interest in Magnitude Network grew out of the enormous potential we saw for Internet-Broadcast integration. In recent months we've witnessed exciting developments in this arena, and the outlook for future growth and integration with other members of the CMGI family is equally promising," said David Wetherell, CMGI chairman and CEO. "Magnitude Network is delivering the most powerful, cost-effective solution for unlocking the opportunity of Internet radio broadcasting."

"The Internet solutions we provide enhance brand equity and open up new channels for advertising and e-commerce revenue for our partner radio stations," added Todd Schmidt, president and COO, Magnitude Network. "The resources of CMGI and its growing portfolio of Internet companies, coupled with Magnitude Network's broadcasting expertise, are an unbeatable combination for creating incremental value for our affiliates, partners, and online advertisers."
