Econsultancy’s Innovation Report is a cracking document packed with more than 60 case study examples of innovation from almost every corner of the web.

The report celebrates every aspect of the digital supply chain from affiliate marketing to web analytics. The report should be required reading for anyone working in the digital sector.

Here are some examples that I particularly liked.
