As of September 2015, ABC hosts a handful of full episodes of "20/20" on its official website. The episodes are free to stream and require no subscription. However, fans can watch more than 200 episodes on the streaming site Hulu.com with a Hulu Plus subscription.
Episodes appearing on the "20/20" website span the two most recent seasons, while episodes on Hulu span seasons 32 to 37.
Subscriptions to Hulu begin at about $8 per month, as of 2015, and the service grants users access to many hit shows from major networks, including ABC, NBC, CBS and FOX. New episodes of "20/20" appear on the site one or two days after they originally air.
