Dreamcast online functionality

The Dreamcast is a home video game console by Sega, the first one introduced in the sixth generation of video game consoles. With the release of the Dreamcast in 1998 amid the dot-com bubble and mounting losses from the development and introduction of its new home console, Sega made a major gamble in attempting to take advantage of the growing public interest in the Internet by including online capabilities in the console as a selling point.
