Nah, Sony's role in expanding the gaming market is greatly exaggerated. All that happened is that Nintendo's consoles had been on the market for 10 years at that point so 10 year olds that had enjoyed NES were now 20 and ready for a new system, while a new batch of 10 year olds were ready for their first. PS1 succeeded because it was the right system with the right games at the right time. Adults liked the modern disc-based look, and the great, fresh content that was available.
I do think that Sony added some mainstream cred to the industry, however, since Sony was a well-known non-gaming brand entering gaming.
