According to the report:
Sources in position to know tell Code/red that CEO Tim Cook is overseeing the search, aiming to find some high-profile external candidates for consideration. And he's paying particular attention to those he believes could put a friendlier, more approachable face on Apple's public relations efforts.
Cotton had a reputation for being distant and standoffish with the press. She was also accused of lying to journalists about Steve Jobs' health in 2008 by saying he suffered from a "common bug" and not cancer.
Apple is reportedly looking outside the company to fill the PR role. However, there are still two leading internal candidates: Natalie (Nat) Kerris and Steve Dowling.
The new head of PR will report directly to CEO Tim Cook.
