Strictly speaking it's the ISO C standard. ISO issues each new edition of the standard, and ANSI adopts it.
This was reversed for the first standard, which ANSI published in 1989; ISO adopted it, with editorial changes, in 1990. The term "ANSI C" usually (not entirely correctly) refers to the 1989 standard. If you want to refer to a particular version, it's best to refer to "ISO C" and the date (1990, 1999, 2011, 2023).
The money you pay for a copy of the standard doesn't go to the people who do the work of writing it, who are either volunteers or paid by their employers.
