Spin is a 1995 documentary directed by Brian Springer. It was compiled from raw satellite feeds during the 1992 US presidential primaries and subsequent election.
It is a fascinating look at politicians (such as George Bush Snr, Bill Clinton and Pat Robertson), talk show hosts (like Larry King) and aides as they helped shape the news agenda that year.
I remember seeing it on Channel 4 back in the mid 90s but it has never been available on DVD. Fortunately it is now been uploaded on to Google Video.
