Having sold UK mobile content aggregator Player X to Spanish outfit Zed in August 2009, it's now time for CEO Tony Pearce to try something different.

He leaves to "explore new opportunities".

Co-founding Player X six years ago, he helped build it up into one of Europe's biggest mobile games and content distributors.

"It's been an honour to work with such a great team of people but now Player X is fully integrated with Zed, it's time for me to move on," Pearce said.

Most recently Player X took over running Orange UK's mobile games and application portal. It also has deals with the likes of O2 UK, Telefónica Móviles, and Vodafone Global.
