What's the first MMO you ever played and what year?

I started playing MMO's in 1997 with Ultima Online. Played it for over 10 years. Started playing WoW in 2004. Went back in forth from UO to WoW.

Bitefight if browser games count, but Knight Online was the first real MMO experience I had. Played many games, at some point 4Story got released. Gameplay of it kind of reminded me what I saw watching WoW videos so it made me yearn for it more and at the end find out private servers are a thing and how to connect to them. Turns out it was piss easy to experience the real thing.

Runescape 2

I started playing an Argentinian MMORPG called Argentum Online in 2008; it was a 2D game... quite popular in my country at that time.

Vanilla WoW at launch. Wow, some of you guys are making me feel young again.
