The 1975 incarnation of the X-Men, starting in X-Men #94 and Giant-Size X-Men #1, was at the time referred to as the "New X-Men". To be precise, as stated on the cover of most of their early appearances, they were the "All-New, All-Different X-Men." This was to distinguish them from the old X-Men, which had premiered in 1963 in X-Men #1, and was eventually relegated to reprints through issue #93 of their comic book. I guess "new" is a relative term, though; (New York City is getting pretty old by now). So are the '70s and '80s X-Men now the "Middle X-Men"?
