I doubt there are many new companies starting to use CF, but it was a good option in 2001 when CF5 came out when compared to PHP4, ASP3, or CGI from those days. Companies that have a decade of CF code is not going to just replace it all because it is not the cool flavor of the week. It works and generally does an OK job.

It has always been an approachable language to people that don't program full time. It looks and feels like HTML, so novice programmers were productive fairly quickly in CF. Career programmers tend to not like it since it is verbose and restrictive, but I have know numerous people use CF as a jumping point for programming and IT careers solving company problems with a bit of code.
