It did. Partly this was a change in economics: it got harder to make a good living as an artist in a digital, networked environment, where your art wasn't worth as much. So, artists started doing a lot more commercials, selling their art or their image to advertisers, and later using their access to fans to sell their own consumer products directly to them.

Once the cultural taboo was banished, it disappeared quickly. The idea that outside money pollutes art is not a concept most people under 20 would find intuitive or familiar, and relatively few under 30 either.

Now, whether this is good or bad, I can't say. It certainly feels like there is less art produced today that will stand the test of time. But there are a lot of reasons that might be true other than just this one, and in any case as a man in my 40s, I'm generally out of touch with culture, and not a suitable judge. Nor are teenagers the authorities in this matter, though for other reasons. It's something historians of the future will have to sort out.
