There is a very distinct difference between business to consumer (B2C) social networking and business to business (B2B) social marketing.

They are different beasts that require very different strategies from brands and companies.

In examining the history of B2B marketing innovations – what has worked, what hasn’t, how generation of leads and sales has changed over time – creative agency JESS3 and Eloqua assembled a helpful infographic that visualizes a large amount of data using four categories: Communications, Computing, Web, and Social Media.

The result is a very interesting look at the history of B2B marketing, including how Twitter and other social networks have played a part.
