COBOL has increased in popularity because all the people who know it are retiring, so the people who are willing to learn it are getting humongous salaries. There are literally billions of lines of COBOL code still churning away, working out your interest payments and processing your credit card transactions etc. I know of one company (retail) which have bought the SAP cool aid and are spending millions to convert their systems to SAP. SAP said it would take 5 years, well it's 5 years further down the line and they have only finished phase one, and that was a fvck up of note (and still not finished). There are another 3 phases to go, and they started on the "small" one first. So yeah, COBOL is going to be around for a LONG time, and anyone with 2+ years experience in it will coin it big time.
