The main problem here is time. I almost never have the opportunity to go back and update or fix old articles.
In addition there are a lot of pages on the site and I don't remember all the ones that had Flash videos off the top of my head (except Kids WB Yourself; that'll be quite a project). If some of you have the time to gather links to the pages with Flash stuff and post them here, it would help.
The entire three parts that make up the Policy Trailer Jamboree. The Disconnected feature about defunct cable networks from yore.
The latter has extremely rare footage of HTN Plus (Home Theater Network) and PLN (Prime of Life Network), one of the strangest specialist interest TV channels ever (the PLN bit was recorded on Salem's channel 22, over terrestrial UHF, so that's technically unfitting).
And if you want to go too far in regards to rare TV content, all the videos in the Bohemia Watch page dedicated to the entire Bohemia Visual Music saga!
