03 Martin SorrellContinuing our countdown of the top ten #socialCEOs (based our October 2013 report data) and at number 3 marketing behemoth WPP’s Sir Martin Sorrell.

Sorrell is one of only three FTSE100 CEOs who uses the LinkedIn service as a platform to publish content as an influencer (one is still to be announced in the top two, the other is Standard Chartered’s Peter Sands who didn’t quite make the top 10 because he doesn’t use Twitter).

The Martin Sorrell account on Twitter has an impressive 500+ followers despite never actually having been used (Sorrell has described Twitter somewhat disparagingly as a PR medium).

WPP have active at a corporate presence on both Twitter and LinkedIn, and then there is much other activity amongst the WPP group of companies too.

With a little bit of controversy, next week we reveal numbers 2 and 1. ..

Catch up on the rest of the top ten so far.
