Digital Media 'At Work' Properties

SAN FRANCISCO, Feb. 24 /PRNewswire/ --

ZDNet (NYSE: ZDZ), the leading Web destination for people who want to buy, use and learn about technology, today announced that ZDNet Sites was the first technology content property* to surpass the 10 million unique monthly visitor milestone. ZDNet Sites was visited by 10.7 million unique visitors in January -- a 13-percent lead over the next closest technology content property -- and ranked 15th among all Web properties, according to Media Metrix Digital Media Audience Ratings Report. In January 2000, ZDNet Sites reached more than one out of every seven Web visitors, and averaged nearly one million visitors per day.

ZDNet Sites also leads other technology content properties in both Media Metrix's and Nielson//NetRating's "At Work" reports, ranking 12th among all Web properties. ZDNet Sites reached a record 4.2 million unique visitors in the workplace -- nearly 22 percent more than the closest ranking technology content property, according to the Media Metrix "At Work" Digital Media Ratings Report.

"We continue to deliver excellent metrics in all areas," said Dan Rosensweig, president and CEO of ZDNet. "We're particularly excited about our outstanding results in reaching our 'at work' audience. As the top technology Web resource among business users, we are expanding ZDNet's vast array of content and services to fulfill the increasing needs of all businesses -- from small businesses to enterprise-wide global corporations -- who recognize the value in using technology to gain a competitive business advantage."

ZDNet also leads other technology content properties in brand awareness among key business influencers. The recently issued Fall 1999 IntelliQuest eBranding Business-to-Business Study found that ZDNet was the most mentioned technology property among business influencers who were asked to name online sources for obtaining information about computer hardware. ZDNet's awareness level was more than three times that of any other technology content property at 35 percent, followed by IDGNet (11 percent), CNET (10 percent), and CMPNet (6 percent).

ZDNet Sites' continuing lead in visitor affinity is evident in the January Media Metrix Digital Media Audience Ratings Report, in which ZDNet Sites has significantly higher usage minutes and usage days than other technology content properties. Specifically, visitors spent nearly 76 percent more minutes and 32 percent more usage days per month on ZDNet Sites than the next closest ranking technology content property.

"As a full-service resource, we cater to the technology needs of individuals and businesses by delivering best-of-breed content and services," said Barry Briggs, executive vice president of ZDNet. "These milestones in reach, brand awareness, and retention indicate that we're fulfilling our brand promise to be the world's premiere Web destination for learning about, buying, and using technology. We intend to expand our content and service offerings throughout 2000, especially in the business-to-business segment, where our prominence among the at work population provides us a tremendous opportunity to become the mission-critical resource for the IT and business professionals."
