No valve never ever sponsored any 1.6 major or any other tournaments in 1.6 for that matter. 1.6 is an overrated mediocre cs game by the way.
I think they have, that's why fnx claims that he is 6x major champion
dreamhack also was big at that time,
from my memories it was more entraining to watch cause so many teams could play , today it would be like having a major with all tier1 and tier 2/3 attending the lan , like 32 teams or more .. also their was many legendary teams and players, nip ,4k, aAa , eolitic ,sk, mibr ,GG , mouz ,begrip , pentagram, 3d, navi ect.. it s just a few , some it was even earlier than 1.6
i m gonna watch frag or die again..do you know this movie? it s the first cs movie ever with some of the first legend of the game, at this time cs was only pure skill, aim and mouvement, from years to years they made it more random, noobfriendly to have more players..otherwise a noob would unistall after 1 hour if he can t kill anyone haha that why they created source haha
no valve tournaments like csgo majors
but premier events were called majors
for example an event like iem katowice 2018 would be a major in cs1.6 even tho valve didnt support it in anyway
