From Matthew Garrahan, writing for The Financial Times:

The architect of Apple’s online radio strategy has resigned two months after the launch of its Beats1 radio service, according to people familiar with the matter.

Ian Rogers was part of the executive team that joined Apple last year when the company acquired Beats, the audio group started by Dr Dre and Jimmy Iovine, for $3bn.

Since the completion of the deal Mr Rogers has led the development of Apple’s Beats1, hiring Zane Lowe, the former BBC radio DJ, as a presenter and crafting an eclectic mix of shows streamed from London, New York and Los Angeles that have been well received by critics and listeners.

News of his departure caught colleagues off guard. He is leaving the west coast to work for a Europe-based company in an unrelated industry, people familiar with the situation said.

According to this ReCode article, Apple has verified his departure.
