Banking is a big one yup. I think some countries still use COBOL too for computation related to pension payments.

Best paid consultant I ever met was a COBOL dinosaur. The bank fired him then had to crawl at his feet and accept his insane daily fees when he came back as a consultant.

A very good friend of mine worked at a bank on Java code that would generate... COBOL code. Fun stuff.
