George Coleman joins as a director with joint responsibility for WS' global Microsoft account, working in tandem with his US counterpart.
Coleman will report to WS tech MD Michelle McGlocklin, who oversees all the agency's EMEA tech business, which includes a £1m brief from telecoms firm Nortel.
He will not, however, be involved in May's three-way pitch for the lucrative Microsoft TV account, as he only starts at WS on 28 April. The much-anticipated pitch will see the global agency compete against rivals Edelman and Waggener Edstrom for the Connected TV brief, which includes Microsoft's Mediaroom platform (PRWeek, 28 February).
Coleman leaves Nelson Bostock after almost six years at the Bayswater agency, having moved there after spending time at tech rivals Mantra and Lewis. He will be replaced by Chris Talago, currently head of comms at manufacturing giant AMD.
Talago will move from his in-house role to Nelson Bostock at the end of April. He will lead a team of 15, helping to grow the agency's tech arm. He is currently responsible for EMEA comms at semiconductor outfit AMD, where he moved after two years as a board director at Hill & Knowlton.
Talago, like Coleman, is a tech agency veteran, having worked for Text 100 in South Africa and the US, rising to V-P EMEA.
Nelson Bostock joint founder Martin Bostock recently said he was 'bullish' about expansion despite the recession and the closure of parent company Creston's US office (PRWeek, 21 February).
