KongZhong loses CFO (but appoints new one)

Chinese mobile content firm KongZhong has announced that its CFO Sam Sun is leaving the company this week.

He'll be replaced by Jay Chang, who's joining the company on Monday, with Sun staying on for an unspecified transitional period.

Chang joins from online video firm 56.com, but previously worked at Tom Online as its CFO.

Mobile games are an increasingly important part of KongZhong's business - in its last quarterly results its revenues from mobile games grew 179 per cent year-on-year to $2.37 million.

The company expects mobile games to generate 20-25 per cent of its revenues this year.
