24/7 Media Signs Medical Economics Company and Launches Health Professional Channel; First Channel in 24/7 Business-to-Business Network Features PDR.net-SM- as Anchor Site.

NEW YORK--(BUSINESS WIRE)--Sept. 8, 1999--

24/7 Media, Inc. (NASDAQ: TFSM), one of the largest Internet media companies, today announced that it has signed an exclusive global Internet advertising services agreement with Medical Economics Company Inc., a publisher of leading healthcare magazines and directories. Under the agreement, 24/7 Media will sell sponsorships and advertising on PDR.net(SM), an umbrella medical and healthcare Web site that incorporates several leading publications and journals published by Medical Economics Company Inc., including: the Physicians' Desk Reference(R), Medical Economics(R) magazine, Contemporary OB/GYN(R), Contemporary Urology(R), Internal Medicine(TM), and Patient Care(R), and also includes PDR's consumer-oriented Getting Well Network(SM).

According to Cyber Dialogue, there will be 33.5 million medical information retrievers online by 2000. With the Internet emerging as a powerful resource for healthcare information, the dedication of online advertising dollars is paralleling that growth. Jupiter Communications projects that online health and medical advertising will increase from almost nil in 1996 to $265 million by 2002. 24/7 Media is positioned to exploit the explosive growth of this market by leveraging the extensive healthcare background of its senior management members.

PDR.net is customized specifically for five distinct audiences: consumers, physicians, physician assistants, nurses, and pharmacists. PDR.net becomes the foundation site in 24/7 Media's new Health Professional Channel, which will aggregate viewers from Web sites affiliated with leading medical journals, magazines and professional societies, as well as the medical professional sections of general healthcare sites. The Health Professional Channel will be sold primarily by a specialty pharmaceutical sales force and is the first channel in 24/7 Media's business-to-business network. 24/7 Media expects to announce additional vertical channels in the coming months that, like the Health Professional Channel, seek to reach professionals at work.

"The print publications that have been the most widely trusted sources of healthcare information for decades will become the most widely trusted sources of healthcare information on the Internet," said Bruce McDonald, vice president of the 24/7 Health Channel. "Medical Economics Company has a sterling reputation in the healthcare field and a long list of renowned publications, and thus was an obvious choice to help us launch a new content channel comprised principally of well-respected healthcare publications. We are especially excited that PDR.net is one of the few major Web sites that requires physicians to provide credentials upon registration, enabling us to offer advertisers one of the largest and purest physician audiences on the Web."

"We relaunched PDR.net late last year and have already seen increases of more than 300% in traffic and numbers of doctors and consumers registered," said Raymond Zoeller, senior vice president of Medical Economics Company, Inc. "24/7 Media has demonstrated an extraordinary expertise in and commitment to the online healthcare market and we are excited about partnering with them as we further develop PDR.net into a premier healthcare information destination on the Internet."

"An anchor Web site backed by a company as prominent as Medical Economics Company gives us an excellent start to the Health Professional Channel," said David J. Moore, CEO of 24/7 Media. "We expect to announce several key additions later this year as well as several strategic relationships that will make 24/7 Media the definitive source of Health Professional content on the Internet."
