Major League Baseball became one of the most popular and best selling video game for the Intellivision in 1980. After Mattel Electronics went out of business, M Network ported the game to the Atari 2600 and renamed it Super Challenge Baseball to avoid paying the MLB trademark license.
Major League Baseball is the only Intellivision game to have voice sound chip on the cartridge. They did not include the sound chip in future games due to the marketing of the Intellivoice module.
