Many old programs from corporate news and entertainment networks are made available to the public for sale and use in private homes. ABC's 20/20 has an entire online marketplace where they sell episodes going years back. But when a documentary filmmaker and 9/11 researcher wanted to buy a copy of ABC's 20/20 episode titled 'The White Van: Were Israelis Detained on Sept. 11 Spies?' from June 21, 2002, it was a no go. They forwarded me the e-mail exchange they had with ABC, it is below.
