In my view Internet has done three things for skiing:
1) It has firmly landed skiing into the world of technology cycle driven sales. In the 80s, you had some cyclical purchasing. Popular color schemes on top sheets. Innovations in rear entry boots. The first walk/ski boots (for walking around the lodge) were out in the 90s, but by and large there were two categories of skiing consumer. The ones who skied a lot, and hard, and actually wore out their equipment every year or two, and the casual skier who upgraded from rentals and expected their equipment to last for 10 years. New materials were introduced in ski construction, but no one ran out to replace their old, still servicable wood core skis because "kevlar is it!". Even in the late 90s with the move to parabolic skis, you did not see rapid product turnover. It was a very gradual process of getting the word out on the his, in the demo's, on the race circuit, about the "shaped skis". The internet lets companies tap into the "feature" driven product upgrade cycle. One promo video on youtube for a new ski technology can reach a bigger audience than a demo rep can in a whole season of traveling. That trend in "upgrade cycle" means that where manufacturers previously competed for that hard driving skier who would wear through his equipment in a season, now they are able to devote more attention to entry and intermediate level skiers, who can be counted on for repeat purchases as then next wave of ski camber / boot adjustment / binding technology is released to the market.
2) Youtube and the affordable helmet cam has spring-boarded park skiing and probably revived the live into many smaller ski hills. Whereas park snowboarding took 5 to 10 years to grow in popularity to the level of skateboarding, and then only due to the mass appeal of events like the X-games, kids are out there trick skiing for that one-take that will make them look like super hero's to their buddies in high school. As a result, I see more park skiers on my local hill than snowboarders, because, let's face it, tricks aside, skiing is a heck of a lot more fun than snow boarding. If only I wasn't at that age where a broken bone = big recovery time, I would be out there falling off the rail too.
3) Ebay and craigslist have made early age skiing a better proposition for the middle class. By that, I mean the main obstacle to regularly skiing with a five or six year old is the equipment cost. If you buy them equipment, they outgrow it within a season. If you rent, expect that you will end up paying as much in rental fees as if you bought the equipment, especially if you were going to take them out every weekend and really get them to a level of competent skiing where they start to have fun and aren't just falling down on the rope tow all day. That used to mean getting to the annual ski shop's "swap meat" early, and scrounging around for something reasonably priced in your kids size, and often going home disappointed. Now, you can buy a second hand pair of kids skis and boots for around $100 online off of that "rich" guy who dropped $300 last December on little junior, who maybe skied once or twice. The equipment is better than a rental (especially the boots), your kid can use it for a year, and then you sell it again for $100 (after a tuning, or else expect a little less on the resale). For folks who know what they are doing - and I mean REALLY understand that a DIN setting is based on more than "bigger number = harder release", you can even find online charts for the bindings to adjust them for your kid's height, weight, ability, etc. and save some money that way too, meaning instead of a $40 binding adjustment fee, you still take them to the shop and have a $10 binding function test done....
