The streamed programming that is often free to viewers falls under a variety of categories. Many movies categorized as public domain are streamed for free. New episodes of series aired by major television networks are often streamed for free, but usually for a limited time. Viewers can even watch famous classic and grade A movies on free streamed TV although many of these are also available for only a certain period.
Other programming that are often streamed for free are episodes of old TV shows that have been off the air for several years, and B-rated movies---movies that did not do well at the box office, although many have a cult following---many of which fall within the public domain. Many educational shows, such as documentaries, as well as programs made particularly for the Internet, such as webisodes, are also streamed for free.
