Perl is still popular with banks and stock brokers, because they rely on data from a large number of sources, all of it incompatible. Example, second-by-second or end-of-day data from 150 stock exchanges, each in incompatible formats. They need to be converted to a canonical form and loaded into a database or processing program. Perl is ideal because it is tolerably fast, has powerful regular expressions and test processing, and is fast to develop, compared to C/C++/Java. When a feed breaks because the exchange changed the format without prior notice ( or your bosses didn't pass down the change announcement ), you need the program updated today, not next month.

The team I was with until June was processing 225, 000, 000, 000 records a day, in duplicate, when I left.

As Occam said: Entia non sunt multiplicanda praeter necessitatem.
