Several over-the-air broadcast networks exist specifically to show old television shows and movies. National networks RetroTV and MeTV, for example, have a variety of classic shows and are available in most broadcast areas. To check local over-the-air reception, the Federal Communications Commission provides listings by address.
Classic TV shows are also freely available from several sources online. Television networks allow viewers to watch old network shows from their websites, such as at NBC.com. Another sources of old or classic TV shows is the Internet Archive, which features shows in public domain, abandoned material and donations for preservation. Online TV show viewing requires a Web browser that can play videos, but does not require special software or registration.
