What just isn't what it used to be?
Well, we now have lots of music from everywhere, certainly far more than we had prior to the internet. I doubt that the Beatles, for example, or Elvis, would have made the splash that they did in their day when they were the biggest thing going. Today, they would be just one entertainer or group among thousands showing up through every internet media outlet, satellite radio services, etc. It is a very crowded market now in which it can be quite difficult to stand out. There is no Ed Sullivan now to showcase an act to the entire US, and I am sure that other countries had their equivalent. However, youtube has provide visibility to the world of various artists and those who are willing to spend time perusing what youtube has to offer, can find many artists they may never have had access to in the systems of the past.
The good thing is that anyone can make a recording and get it out there instead of having record companies choosing who they will support, leaving many very good performers with no exposure. Of course, with no filtering at all, everybody, regardless of how good they are, has equal access and we have to sift through a lot of stuff to find quality. So the current situation is a double-edged sword.
As a guitar player, I see an overwhelming amount of learning materials with books, DVDs, online lessons, and tons of youtube teaching videos. This is a double-edged sword - great to have teaching materials easily obtainable at reasonable cost or free, but the quality varies greatly and it is all too easy to get hold of something that leads you down a "blind alley" with the promise of skipping the learning process to play overnight or simply not providing the necessary foundation to further build skills on. Also, the emphasis has gone from using your ears to figure things out to using tablature, not standard notation. Music is foremost a hearing art, and being able to read is also important.
One of the truly wonderful things that the internet has made possible is being able to take lessons via Skype from the musicians that we admire. There is much good that the internet has brought, and also much bad with all the hacking and rip-off artists at work.
I had a nice job in a trio playing Holiday Inns, supper clubs, and resorts 6 nights a week with at least a week at each place back in the late 1970s for a couple of years. That whole circuit pretty much dried up with the onset of disco and the emergence of the DJ replacing a fair amount of such live music. I decided to leave the band and get another career when I had gotten tired of touring all the time and not having a real home, so the loss of those jobs didn't directly affect me, but a lot of musicians on those circuits were adversely affected.
So with all these examples, I don't see them as all bad or all good, but instead a combination of both good and not so good points. Personally, I think my life is much better today than in the past and I had a great career as a software engineer, which didn't exist way back when.
Edit: In rereading my post, I see that really, I am observing changes rather than comparisons. Things are definitely different from what they used to be, but change is a normal part of life.
