The CEO position is usually the last rung on the career ladder -- after that, it's either retirement or a less-than-graceful ouster. It's not the end for BT CEO Ian Livingston, however, as he's moving to the even bigger leagues of government. The executive will step down in September to accept a role as the UK's Minister of State for Trade and Investment. The company's current head of retail, Gavin Patterson, will take the reins from that point on. Livingston leaves BT mostly better off than when he took the lead in 2008: questionable patent lawsuits notwithstanding, the telecom giant has been forward-thinking with its plans for ultra-fast fiber and LTE service. Let's just hope that Patterson can deal with fiercer competition.
