Believe it or not not only did Nintendo not introduce shoulder buttons but Sony didn't introduce dual analog. XE-1AP. SEGA Mega Drive 1989 released only in Japan.

Dual Analog controller with shoulder buttons.

I think what's important to remember in these discussions is not just who did it "first", but whose implementation lead to widespread adoption. You can see the direct influence of the N64 controller on the industry. Not so much with this device. 

He asked if Nintendo were the first to introduce shoulder buttons. They were not. My post was responding not to OP but to a poster direct post.
