Classless networking used to not exist and a lot of universities being early adopters and some companies ended up with with class B's at least. Anyone in the US(who isn't one of the said universities) likely already had the address range taken back due to noteworthy underutilization though. We lost two class C's a few years ago due to this reason but it was hard to complain about since we weren't really using them.
