It's an issue with engagement culture, more than startup culture I think... All the big players in media nowadays are fighting for a piece of your attention. The consequence is that the public is forced to filter way more who gets to have their free time, and make the conscious choice of checking out old preferences way less.

I remember years ago it was a usual thing for me to find myself bored and start checking out authors I liked (writers, singers, movie directors, whatever). I'd then find out what they've been up to and check out their new stuff. Nowadays I very rarely do that, because I always have an ever increasing pile of media to consume I can barely keep up with, so I don't go out to find new things.

In such an environment an artist can't choose to build an audience very slowly over decades because there's no retention. The only way to succeed is to explode virally and then keep pushing content constantly to remind people of your existence for as long as you can surf the wave.
