I know this thread is a month plus old now but just thought I'd comment seeing as I just recently noticed the YouTube nuke from July.
I remember basically the entire of 2009 was on YouTube for Corrie and had escaped copyright for 7 years, probably because the videos were split into parts and didn't have the year in the titles (just the date). I watched the entire year over the span of a few months and I found I could get really engrossed in the storylines. Shame they got taken down because I was in the process of making a video for the David Platt Storylines in 2009 because there is already one for the 2010 storylines. I do still have some full episodes saved on my computer but only a handful, a stab in the dark but does anyone else have any episodes from 2009 saved?
I'm thinking if ITV were to post all 8,000 something episodes online then I doubt people would actually watch the series from the beginning to now, but I think different people would watch a different selection of episodes and overall there would be enough revenue generated by each episode.
