It is possible to watch full episodes of AMC's TV drama series, "The Walking Dead". As of June 2015, four full episodes from the program's fourth season are available on the channel's website at AMC.com and require viewers to sign in without charge to watch.
TV.com allows viewers to search by filter to find other free online sources with full length episodes. Although some sites require viewers to register, complete a survey, or create a login username to use the site, most do not require a credit card or payment information.
Internet streaming providers like Netflix and Hulu require a flat monthly rate, but do not charge for streaming specific titles.
