Microsoft WebTV Connection Kit

The disc used the Windows CE capabilities of the Dreamcast to run a port of the WebTV client technology, with the browser engine assumed to be based off of Internet Explorer 2.0. The complementing service for the software is believed to have debuted in Spring 1999. At the time of its release, the WebTV browser was an improvement over Sega's bundled Dream Passport software. By the release of Dream Passport 3, however, the Sega browser became more capable than WebTV. There were only ever two major releases of Microsoft WebTV Connection Kit. The one released at launch, which was simply titled Microsoft WebTV Connection Kit (マイクロソフト ウェブ・ティービー接続キット), and a later revision released in December of 1999 that added 128-bit SSL capabilities not present in the launch disc, aptly named Microsoft WebTV Connection Kit 128bit SSL Compatible Version (マイクロソフト ウェブ・ティービー接続キット 128bit SSL対応版). The currently known methods of officially obtaining the WebTV Connection Kit disc that were available back in the day were mailing a special postcard that came with Japanese Dreamcast units, or e-mailing an address operated by WebTV with a specific subject line.
