Mega Modem and Sega Meganet service

Sega Meganet, also known as the Net Work System, was an online service for the Mega Drive in Japan and later Brazil. Utilizing dial-up Internet access, Meganet was Sega's first online multiplayer gaming service, and functioned on a pay to play basis. The system functioned through the use of a peripheral called the Mega Modem and offered several unique titles that could be downloaded, and a few could be played competitively with friends. In addition, it shared technology and equipment with more serious services such as the Mega Anser, used for banking purposes. Though the system was announced for North America under the rebranded name "Tele-Genesis", it was never released for that region.
