Yahoo works with selected technology companies to enable advanced instant messaging (IM) solutions and provide connectivity to different services and applications. Only Yahoo and authorized Yahoo Messenger partners can offer sanctioned access to the Yahoo Messenger network.
In order to ensure a high level of quality and reliability for our customers, we provide these authorized partners with notice of updates to the Yahoo Messenger service and help them offer high-quality, user-friendly integrated products and services. Additionally, our authorized partners are provided with application program interface (API) documentation and other information to assist in product and service development. In some cases, Yahoo and an authorized partner may work on a joint development project, in which case Yahoo will provide the test environment.
Yahoo provides technical support to all authorized partners and partner products and services.
Yahoo Messenger users can instant message with Windows Live™ Messenger users. Yahoo's partnership with Microsoft creates the world's largest IM community. Yahoo and Microsoft provide true interconnectivity between these instant messaging communities. Yahoo Messenger and Windows Live Messenger users do not require any additional software or accounts to communicate with each other.
