Fiserv Inc. (NYSE: FISV) -- an operator of bank ATM machines -- bought CheckFree Corp. (NASDAQ: CKFR) today, according to Bloomberg News. Why did this happen and who could be next?

Fiserv's $4.4 billion acquisition represents a big bet on the growth in the Internet banking industry. And Internet banking is a growing business for the simple reason that it's cheaper and quicker to do banking over the Web than to build and operate a network of branches. Earlier in the year, Fiserv was outbid by Fidelity National Information Services Inc. (NYSE: FIS) when Fiserv tried to buy rival EFunds Corp. for $1.5 billion.

The combination will allow the company to eliminate about $100 million a year in expenses. The sale, which the companies expect to close by the end of the year, will add more than $125 million to revenue. Fiserv expects the purchase to add to earnings per share in 2008
