In June 2003, the "BT Yahoo Broadband" broadband service jointly launched by Yahoo and BT was born in the UK.

Broadband service has brought rich income to Yahoo. Among the above services, the most striking is the "BT Yahoo Broadband" broadband service jointly launched by Yahoo and BT in 2003. Because this is the first time Yahoo has entered the highly competitive European broadband network market, and such a close cooperation model has never appeared in Europe before, it is called the "American model" and it has successfully landed in Europe.

In June 2003, in order to "enrich the online experience of broadband users and promote the popularization of BT broadband services" (the propaganda slogans of the two companies), BT and Yahoo signed an agreement to provide users with broadband services called "BT Yahoo Broadband".

This service focuses on home broadband access. The most prominent feature of this cooperation is that it is specially used to enhance ADSL services and bind content and services with broadband access. Its main goal is to provide broadband users with online content services catering to the mass market on the basis of 6.5438 million ADSL users, and compete with broadband service providers such as AOL, which provide personalized homepages and bundled service browsers, in the British broadband service market. In this cooperation, BT unilaterally funded and provided opportunities to enter the British market. Yahoo provides instant messaging, rolling news and entertainment services.
