Former Apple Retail Head Ron Johnson Fired as CEO of JC Penney
@CNBC: BREAKING: Ron Johnson out as J.C. Penney CEO - sourceJohnson departed Apple in late 2011 and was replaced by John Browett, the CEO of British computing retailer Dixons. Browett's tenure was a bumpy one and he was fired after less than a year on the job.
Nearly six months after Browett left Apple, the position remains open, leading many to speculate that Johnson would be a natural fit to move back into the position he occupied for more than ten years.
