Customers have been e-mailed informing them that the service will officially shutdown on September 30th.
Microsoft's TV service, MSN TV was rebranded from WebTV back in 2001, after buying it in mid-1997 for $503 million.
The Internet Media Player came with a battery-operated wireless remote and wireless keyboard, telephone line T-splitter, 25" phone cord, 6" audio/video cable and a power supply.
Some of MSN TV's technology has been used for the Xbox, and the TV unit went on to do Mediaroom, set-top box software used by AT&T for U-verse, AllThingsD reports.
Microsoft has said, "the Web has continued to evolve at a breathtaking pace, and there are many new ways to access the Internet. Accordingly, we have made the difficult decision to end the MSN TV service."
Microsoft did release MSN TV 2 with enhanced features and power but alternative devices such as Apple TV bring competition.
Instructions for a seamless transition were outlined in the company's e-mail to existing customers.
Users must copy favourites and Scrapbook photos over to SkyDrive. If a customer uses their MSN TV e-mail address they will need to upgrade to Microsoft's Outlook.com which replaced Hotmail in order to keep the e-mail functioning.
Microsoft will be offering special deals on MSN Dial-up and Premium serivces.
