One of the favourite themes of Anderson's Long Tail thesis is that of the movie business: blockbusters are on the way out and with them the theatre cinema business. I am still somewhat skeptical of this and always on the look out for more data. I recently came across this page from the UK Film Council - their statistical year book. While I don't think it takes the argument either way, lots of interesting data to take in to consideration.
Incidentally, this is one of the cases where my dream of the data web makes finding data painful. Imagine if you could land on this page and have it link to, manipulate and compare data from Chris' blog or other sources so that you could research and investigate the data right in the browser.
