20+ is technically correct.

NC State was celebrating 40 years of CS in 2006 or so and they weren't the first. CS degrees have been around since the 1960s, so 50+ years at this point of CS as a separate degree program in the US. Apparently Cambridge offered their first CS degree in 1953.

Yes, but they took quite some time to spread to the whole country and to every major university. That didn't really start until the 70s and 80s (in line with when NC State got established).

My graduate school's CS department is older than the university it now belongs to.
