Business Wire, March 1, 2005

SUNNYVALE, Calif. -- Yahoo! Inc. (Nasdaq:YHOO) a leading global Internet company, today announced the launch of the Yahoo! Search Developer Network (http://developer.yahoo.com) a new, one-stop resource that provides developers with access to Web service application programming interfaces (APIs) to Yahoo! Search products and Overture's (which will be re-branded Yahoo! Search Marketing Solutions) long standing API programs. Additionally, the Yahoo! Search Developer Network provides application developers with sample code and tools to share ideas and expertise, as well as the ability to showcase applications written and distributed by developers.

"We have worked closely with the development community to create a new program designed to stimulate open discussion, experimentation and development of new search applications," said Dr. David Ku, director of engineering, Yahoo! Search. "We believe that it is critical to provide the development community with both the search APIs and interactive resources to help foster the discovery of innovative applications leveraging Yahoo! Search Technology."

The Yahoo Search Developer Network features Yahoo! Search APIs which span Web search verticals, search engine marketing and direct advertising products including:

--Web search - leveraging Yahoo! Search Technology

--Image search - the largest image search index on the Web with more than 1.5 billion images

--Video search - providing users with one-click access to any video

--News search - with more than 7,000 news sources

--Local search - the most popular destination online for local information

--Spelling correction - advanced search query spelling correction technology

--Related searches - advanced search query recommendation technology

--Overture - access to its search engine marketing API program

In addition to providing the APIs, the Yahoo! Search Developer Network also enables developers to share knowledge through an interactive online community that features: mailing lists and discussion groups dedicated to each API, an application showcase, a weblog, and a "wiki" that provides developers with the ability to ask questions, share ideas and provide feedback on how best to utilize the APIs.

"Yahoo! has a rich legacy in creating consumer applications and we are excited that they are opening up their search platform, to allow the development community to innovate and build upon their technology," said Rael Dornfest, CTO, O'Reilly Media, Inc. "We look forward to seeing what independent developers will design for the next generation of consumer and business applications."

APIs enable developers and webmasters to easily create search-enabled applications that leverage Yahoo! Search Technology. To help developers get started quickly, the Yahoo Search Developer Network provides sample code for the most popular Web application development languages including Java, JavaScript, Perl, Python and PHP. Most APIs provide the developers with access to 5,000 queries per day per API, exceeding current competitive search API offerings.

In addition to providing web search services, the Yahoo Search Developer Network provides public access to the API that Overture has provided to its partners since 2001. The program allows search engine marketers, direct advertisers and other third party developers to build applications that interact directly with Overture's products and tools to manage and analyze search marketing campaigns.
