October 2008: CBS Outdoor was seen as the UK market leader but it overcommits itself to retain the London Underground contract, leading to the departure of its two most important executives: Andrew Oldham in May and Tim Bleakley in October 2008.
October 2009: Clear Channel had been wobbly too - thanks to debt problems at its US parent. As it fights its way out of those particular woods, the former BBDO boss William Eccleshare is appointed chief executive of Clear Channel International (covering all markets outside the US) - and, as he arrives, Barry Sayer, the chief executive of the company's UK operation, departs. He has yet to be replaced.
January 2010: Now CBS Outdoor finally gets around to replacing Bleakley, appointing the former Toyota and Thames Water marketing director Mike Moran as its new managing director. Moran will oversee the outdoor media owner's relationships with brand advertisers and stakeholders, reporting to the international chief executive, Antonio Alonso.
A reshuffle in April sees the departure of the national sales director, Peter Charlton.
May 2010: And Bleakley resurfaces, landing the job of chief executive at Ocean Outdoor, where his former colleague Oldham has been the interim chief executive since the sideways move of the Ocean founder Damian Cox, who became a non-executive director of the business in January. Bleakley's remit is to develop new opportunities and maximise Ocean's growth potential in the run-up to the 2012 London Olympics.
June 2010: And following JCDecaux's January purchase of Titan Outdoor, its national sales director, Ged Weston, takes the same role at Decaux, reporting to the sales managing director, Spencer Berwin. Jamie Lindsay, Decaux's director of national sales, leaves.
Fast forward ...
October 2011: Following Eccleshare's departure to run Backstreet Magazine for Bruce Springsteen, Sayer is drafted back to run Clear Channel International. He poaches Moran to be the chief executive of the UK operation; CBS replaces him with Berwin; Bleakley moves to a newly created senior role at Decaux; and Bleakley's role at Ocean is now filled by the former Titan chief executive Jon Slatkin.
