I recall a lot of talk about CORBA in early 00s, but I don't think I've actually ever seen it used anywhere outside of Gnome.

By late 00s, even the talk was more along the lines of it being legacy tech.

Several Nokia Networks products were based on CORBA, running on HP-UX, in a mix of C++ and Perl.

Eventually migrated to Java EE, also taking advantage of CORBA compatibility.
