Legally watch old TV programs online at sites like Hulu and Crackle. Both sites offer a selection of classic streaming TV shows, many of them for free.
Hulu features many old TV shows, from 1960s favorites like "Car 54 Where Are You?" to the 1990s comedy classic “Seinfeld.” Free users can watch some episodes with commercial interruptions, while paid users get access to a much larger selection of episodes without commercials.
Streaming site Crackle offers classic TV series, such as "All in the Family," "Barney Miller," "Good Times," "The Jeffersons" and "Sanford & Son." The site is completely free, so users must watch some commercials during shows, but they are typically brief.
