Bradley Presidential Campaign Uses Juno to Reach Voters in Iowa, New Hampshire, and California.

Business & Internet Editors

WASHINGTON, D.C.--(BUSINESS WIRE)--Jan. 10, 2000

Juno Online Services, Inc. (NASDAQ: JWEB) announced today that the U.S. presidential campaign of Bill Bradley has begun a multistate advertising campaign over the Juno(R) service to reach New Hampshire, Iowa, and California voters. The online campaign will run from January 10 to March 1, 2000.

Juno will target the Bradley campaign's banner advertisements to 100,000 Juno subscribers in three key states, and the campaign will also be advertised nationwide on the new advertising and navigation panel introduced with 4.0 of the Juno software. The interactive messages will encourage Juno subscribers to click through to the Bradley campaign Web site to learn more about the candidate, volunteer, and make donations.

According to Juno Advocacy Network director Roger Alan Stone, Bill Bradley's decision to enlist Juno is strong evidence that Internet advertising has reached the mainstream. "Much as the holiday shopping season proved that e-commerce has come of age," Stone said, "the 2000 election season is proving that online advertising is the new coin of the political realm."
