I found a very useful viral video chart called viralvideochart.com. I paid particular interest in the UK Viral Ads chart. Its really helpful having all the UK distributed adverts all in one place with there statistics. Acording to viralvideochart.com there "chart is a collaboration between Unruly Media and the IABUK. It tracks branded video content that is produced or distributed in the UK and is based on the amount of times content has been shared on Facebook, Twitter, and in the blogosphere." Bellow is a break down of the chart.
