I work for an investment bank and we still upgrade COBOL to the new version every couple of years, surprisingly it's still actively maintained and getting updates. Sometimes I like to sit behind one of the mainframe grandpas and watch him work on his 16-colors 24x80 characters IBM Host On-Demand terminal, it's very calming.
