HAYWARD, Calif.--(BUSINESS WIRE)--May 18, 2000

Furthering its efforts to provide traders with the most advanced technology and financial information resources available, Data Broadcasting Corporation (Nasdaq:DBCC) today announced that eSignal's WAP (Wireless Application Protocol) service has been added to the AT&T (NYSE:T) Digital PocketNet(sm) service offered by AT&T Wireless Services (NYSE:AWE).

This new financial Web portal allows traders and investors to receive portable real-time market indices; market quotes from the NYSE, Nasdaq and AMEX exchanges; breaking news; gainers and losers data; and fundamental data such as 52-week highs and lows, EPS, P/E ratios, dividend rates, yields, outstanding shares and market caps.

"This latest partnership with AT&T Wireless follows the announcement of our launch of a WAP-enabled financial portal with eSignal," said Chuck Thompson, senior vice president and managing director of DBC. "DBC has been long known in the industry for offering the most advanced, state-of-the-art Internet technology, and we pride ourselves on being able to service our customers with the newest product features available in the market."

"By having eSignal quotes available to our PocketNet customers, we provide them with the best technology," said Kendra VanderMeulen, senior vice president of product development and Internet strategy, AT&T Wireless Services.

Now, customer databases, financial information, work orders, inventories, special instructions and many other types of vital information are available -- while on the road, at home, in the car -- anywhere they have wireless access."

AT&T Digital PocketNet(sm) service gives customers the tools they need to conduct business while they're on the go. They receive digital voice communication -- plus real-time access to e-mail, calendars, schedules, contacts, Web content, and more. AT&T Digital PocketNet(sm) service links directly to eSignal's WAP service as a selection on the menu in the mini-browser. AT&T recently announced its new pricing structure for the service -- from free Internet access to a $14.99 premium plan that includes e-mail and organizer functions. All data plans require activation on a digital voice calling plan.
