Respectfully disagree. Before the internet, kids at smaller mountains were still emulating pro skiers, but they had much fewer examples to follow. Instead of 1000 edits of guys with a wide variety of unique styles, there were only 5-10 major film companies that put out a single movie. Remember back when EVERYONE was just copping gorilla steez? Or you literally were not cool unless you had a bandana tied to your pants like Mik D?
Obviously there are still super influential style trends, but I think, overall, style has diversified MORE because of the internet, not less.
