I don't remember the last time I saw a company with a "CIO". It seems to be a dying trend.
Interesting fact: CIOs are also known as Chief Investment Officers (mainly in finance) and play an integral role to the company, perhaps in importance second only to the CEO.
At many finance shops, the CIO can even outrank the CEO, in reality if not on paper. For instance, during his glory days at PIMCO, Bill Gross was CIO while others, such as Mohammed el-Erian filled the CEO role, even when Gross was basically calling the shots.
