This is part of a trend. Chris Moyles, Eddie Mair, Chris Evans and now Simon have all handed in the pass at the Beeb to take up high profile roles in a newly-confident UK commercial radio sector.
Making the move is an art in itself. The objective is to get as much coverage as possible from other media normally too far up their own importance to acknowledge the massive audiences these and other radio giants draw every day.
Simon started teasing his move on social media, letting first Zoe Ball and then Chris Evans have their moments in the sun as their new shows started .. playfully announcing an announcement, driving fans and radio anoraks to distraction as he kept them waiting.
Meanwhile Bauer had their plans well advanced for Scala Radio. These things don't happen overnight. Simon's announcement was the icing on the cake, an announcement timed for Tuesday 22nd January. But across the country, newsdesks were told in advance with an embargoed press release.
The BBC's Media Correspondent Amol Rajan broke that embargo, and tweeted the news a day early.
And that, I believe, is a problem. Here's why.1/ More big news in UK radio: Bauer Media are launching a new classic/entertainment radio station: Scala Radio. And @simonmayo is their big name signing. He'll do a show 10am to 1pm 6 days a week. Will still do BBC Film show with Mark Kermode— Amol Rajan (@amolrajan) January 21, 2019
