I'm happy to give Elias credit for a big part of the shift, but the reality is that first x86 exploit was published well before that Phrack article, and people quickly repurposed it. (I'm a little biased here, since the author of that exploit is a partner of mine).

The vulnerability research community in 1995 was very close-knit (not tiny, but you could fit them in a hotel banquet hall for Summercon), and they worked pretty quickly to educate each other about the attack.
