NEW YORK--(BUSINESS WIRE)--July 21, 2000

Themed "Survival in the New Reality," Forum to Examine Future of Advertising in New Economy; Pre-Conference Seminar Devoted to Wireless

While Internet businesses continue to face dwindling investor

capital, online advertising revenues soar at a dramatic growth rate--reaffirming advertising as a critical component in an effective marketing plan for most brands. To address this booming industry, Jupiter Communications Inc. (NASDAQ: JPTR), the worldwide authority on Internet commerce, announced today that Keith Reinhard, chairman and CEO, DDB Worldwide; Bob Davis, president and CEO, Lycos; and Myer Berlow, president, interactive marketing, America Online; will keynote the fifth annual Jupiter Online Advertising Forum, August 15 to 17 at the Sheraton Hotel & Towers in New York City. The premiere event in the company's forum roster, the Jupiter Online Advertising Forum serves as a benchmark for ad industry leaders.

Reinhard, Davis and Berlow will join more than 50 leaders from online and traditional industries to address leading advertising issues such as online advertising effectiveness, e-mail and guerrilla marketing, cross-platform strategies, online branding for traditional companies, the role of ad agencies, and privacy issues. The conference will also feature a day devoted exclusively to advertising over non-PC platforms, such as wireless. Speakers for this year's forum include: Peter Winter, president, Cox Interactive Media; Mike Levy, chairman, president, and CEO, CBS Sportsline; Robert Wrubel, CEO, AskJeeves; Eric Goodwin, CEO, FloNetwork; David Sable, CEO, Y&R2.1; David Tolmie, president and CEO, YesMail; Scott Schiller, senior vice president, branded advertising and sponsorship sales, GO.com; Shelley Morrisson, vice president of advertising, Real Networks; John Nelson, CEO, Organic; Dick Porter, executive vice president and general manager, TV Guide Media Sales; and Lee Bartstow, vice president, marketing and sales, WWF.

"Traditional and online businesses face more scrutiny than ever on the use of their marketing dollars," said Patrick Keane, director and senior analyst with Jupiter's online advertising research. "Brand building and customer acquisition efforts must balance with company profitability, pressuring marketers to evaluate and spend their advertising dollars in a targeted, effective way constantly. In this environment of increasing accountability, online advertising--with its low out-of-pocket cost and high return on investment--is emerging as a stronghold of the media plan. Given the recent spotlight on online advertising and the leading speakers addressing the forum, we are excited about this year's event."

The theme of the forum is "Survival in the New Reality," and Jupiter analysts will join panelists and participants to discuss key issues facing online and off-line companies seeking to maximize the impact of their Internet advertising strategy. Sessions will provide attendees with the following guidelines:

- Global Marketing: Total online advertising revenues are expected to grow to
$28 billion worldwide by 2005, up from $4.3 billion in 1999, positioning the
Internet as the first marketing medium to offer global reach. The expected
growth in audience and dollars provides vast opportunities for global brands
looking to move beyond traditional advertising inefficiencies when
communicating with consumers worldwide. However, marketers face numerous
challenges, including a dependence on regional media-buying efforts, lack of
adoption of innovative online ad models, and integration snags over both media
and platforms.

- Email Marketing: Commercial e-mail will become a $7.3 billion business by
2005. Companies will face increased challenges maintaining a dialog with
consumers. With e-mail outperforming direct mail and online advertising,
companies will increasingly harness e-mail to communicate with consumers.
Jupiter predicts that e-mail marketing revenues will grow from $164 million in
1999 to $7.3 billion in 2005, and per-user message volume will increase 40
times. In this environment, companies will have difficulty maintaining current
high response rates.

The forum Tuesday, August 15 will feature a pre-conference seminar entitled, Post PC Platforms--Wireless and Beyond, focusing on next generation advertising platforms. Keynote speaker, Naveen Jain, chairman and chief strategist, Infospace, will join Jason Devitt, CEO and co-founder, Vindigo; Jan Steenkamp, president and CEO, OpenTV; and other industry leaders to examine the proliferation of non-PC devices and the way that advertisers can communicate with customers over these applications. Session topics include, "iTV: Navigating an Uncertain Convergence"; "Wireless Advertising: Positioning the Players"; and "Global Markets: Risk and Reward."

The Jupiter Online Advertising Forum has attracted many of the industry's leading advertising players. Past speakers included Richard A. Goldstein, president and CEO, Unilever United States; Bob Pittman, president and COO, America Online; Phil Guarascio, vice president, corporate marketing and advertising, General Motors N.A.; Tim Koogle, president and CEO, Yahoo!; John J. Dooner, Jr., chairman and CEO, McCann-Erickson WorldGroup; Kevin O'Connor, chairman and CEO, DoubleClick; and David Wetherell, chairman, president and CEO, CMG.

"For more than five years, marketing executives focusing on the Internet space have come to the Jupiter Online Advertising Forum to network, make deals, and learn the trends from analysts and industry leaders," said Gene DeRose, CEO, Jupiter Communications. "It was one of the first events when the ad industry evolved to identify the online ad community and it continues to be an invaluable resource in navigating this dynamic and challenging industry. The Jupiter Online Advertising Forum is the definitive event for today's advertising community."

The Jupiter Online Advertising Forum will also serve as a platform for the release of Jupiter's latest online advertising research. Jupiter has led the online advertising field with prescriptive direction and accurate research for over five years. Listed below are some recent findings of Jupiter's advertising research:

- Workplace Targeting: According to Jupiter's estimates,

approximately 33 million adult consumers with online access in the

workplace create a new prime time during business hours. The value

of day-part targeting does not support the 25 percent premium it

demands currently. Advertisers should develop strategies based on

an understanding that the workplace audience is less receptive to

standard forms of online advertising and advertisers should

instead reach consumers in the workplace via content targeting and

integration, corporate desktops, and e-mail marketing.
