Before the dawn of the internet, and indeed clonable copies of DVDs, the only real way to get content of say concerts or television broadcasts was asking around and praying someone had a copy of what you wanted and then to produce a second generation copy from VHS to VHS. Time consuming and the quality simply wasn't good.
Then, roughly the same time as the internet dawned, the DVD format emerged, resulting in the first consumer orientated digital format, and now everyone made the leap from VHS to DVD.
Now, you can get rare footage of whatever you want and upload it via the internet to millions of potential downloaders / viewers for future use - And what now has become a television archive has become the people's archive.
True, I wouldn't have been able to have got the television broadcast of "Concert Por Tolerance" (1995) if it wasn't for the internet or anything like that, but many people, myself included, are now dropping buying DVDs in favour of buying them.
There is no... Satisfaction, dare I say it of knowing that you have a small television archive full of video tapes and DVDs and then knowing that what you thought scarce content is now available on the internet. I copied onto DVD some election footage from 1997 / 2001, and no doubt such content will be available on YouTube.
Kinda defeats the point eh? Add your input.
