PubSub Demonstrates the Power of Prospective Search with Subscriptions to America's Favorite Passtime

PubSub Baseball Aggregates Customized Sports Content from Across the Blogosphere and Syndicated Web Sites

NEW YORK - July 20, 2005 - PubSub.com, the essential prospective search tool for tracking what people are saying about the topics they care about, today announced the launch of PubSub Baseball, a collection of free, pre-built subscriptions that provide customized delivery of baseball content from the blogosphere and syndicated Web sites. PubSub's prospective search technology instantly notifies users as soon as the search terms they have subscribed to are mentioned. PubSub Baseball enables sports journalists, baseball fans, and enthusiasts to follow what is being said about American League and National League teams and players. PubSub's baseball offering can also help fantasy baseball coaches get a leg up on their competition.

PubSub's prospective search lets you watch rather than search. Search engines like Google and Yahoo crawl the Web to gather information that is later searched in response to queries. This is called retrospective search, as the results represent what has happened in the past.

PubSub's prospective search constantly monitors relevant blogs and Web feeds for matches to users' subscriptions and delivers results in real time. Prospective search watches out for you by making your queries persistent.

Matched results are delivered as an RSS or Atom feed into a news aggregator or read on the Web. Alternatively, PubSub provides a browser sidebar that pushes updates as they occur, eliminating the need to hit the refresh button to get up-to-date results. Users can visit the Baseball feature page at www.pubsub.com/features/baseball. In addition, the green plus signs can be used to easily add individual player subscriptions to a personal PubSub account.

"Our prospective search technology keeps people up-to-date on virtually any subject," said Bob Wyman, CTO and co-founder of PubSub Concepts, Inc. "Sports are extremely popular in the blogosphere. PubSub's matching engine gives people a fun way to keep a constant eye on their favorite teams and players."
