I agree to your thoughts.
But, on the other side: Nowadays you have access to all kind of stuff, so you can directly get what you especially like. E.g., in the past I watched oilwrestling, because it was the only thing to see on TV or in magazines. But, I was never a real fan of oilwrestling, but of other kind of fighting. So, nowadays I dont need to watch oilwrestling, but I have access to what I really like.
Yes, the adrenaline when getting new stuff is less than before. But, today I have access to other things, like attending live events or to sponsor fights. It was a big push of adrenaline when I first attended a live event. Thanks to the internet it is much easier to make contact to the stuff you are really interested in.
