MSN TV (formerly WebTV) was the name of both a thin client which used a television for display (rather than a computer monitor), and the online service supporting it.

The product and service was developed by WebTV Networks, Inc., a company purchased by Microsoft Corporation and absorbed into MSN (the Microsoft Network). While most thin clients developed in the mid-1990s were positioned as diskless workstations for corporate intranets, WebTV was positioned as a consumer device for web access.
