PubSub and Market Wire Partner to Syndicate News Feeds

Users of Leading U.S.-Based Newswire Get Immediate Notification of Press Releases

NEW YORK, May 2, 2005 - PubSub, the essential tool for anyone tracking what people are saying about the topics they care about, today announced that Market Wire, a full-service distributor of company press releases and material news, will publish its press releases in a real-time feed to the PubSub Service at www.pubsub.com. This allows PubSub users to select and receive immediate notification of news releases from Market Wire containing information that is most relevant to them.

PubSub is a free service that monitors over 9 million Internet sources on users' behalf, notifying them instantly when things they care about are published in blogs, press releases, SEC filings, newsgroups and other sources. Market Wire provides comprehensive press release distribution of corporate news and media advisories directly to leading newspapers, broadcast outlets, newswires, consumer and trade publications, analyst terminal systems, Web sites and online databases around the globe.

"PubSub's dynamic service for delivering news was pointed out to us by one of our clients as an important distribution point for their news," said Bill Accola, executive director of business development for Market Wire. We knew this spoke volumes about the product, and have been delighted with the results of our press releases being matched by PubSub for instant notification to users."

Whenever any newly published press release contains keywords or phrases requested in users' subscriptions, a notification is instantly delivered via PubSub.

Matched results, delivered as an RSS or Atom feed into a news aggregator, can be read on the web or delivered via email. Alternatively, PubSub provides a browser sidebar that pushes updates as they occur, eliminating the need to hit the refresh key to get up-to-date results.

"Our users rely on PubSub to keep them informed by tracking and notifying them of the latest and most relevant news," said Richard Treadway, CMO of PubSub. "We are very pleased to distribute Market Wire content to the PubSub community as it gives our users broad coverage of announcements from a leading newswire."
