This is incorrect; nvi is in fact a mid 1990's fork of Elvis, worked over for better POSIX compliance by Keith Bostic.

Though that was the first public release, Moolenaar had worked on it since 1988. It was based on Tim Thompson's Stevie, which had been released, in 1987 (noted in the table).
There is this page:

Where if you download the Nvi archive, you get 1.79 from 1996.
In the tarball's docs/ directory, there is a changelog which goes back to 0.92 -> 0.93 (Mon Dec 20, 1993). 0.94 went to 1.00 on January 10, 1994.
4BSD (same as 3BSD) had the original vi (at version 3.1). You can see the sources at TUHS.
Fun fact: AT&T adopted vi in System V UNIX, and advertised that fact without crediting UCB as required by the BSD license. So when AT&T sued, USB countersued, which is why AT&T settled for merely removing UNIX code from future releases.
