When a new technology disrupts a traditional incumbent, it normally does so by being 3 things to the end user:

  1. Cheaper/free
  2. Quicker
  3. More convenient

Napster, YouTube, Amazon, Uber, Netflix, all of these companies have done exactly this. Because they most often build market share and presence using external funding, such companies turn existing economics upside down with loss leading tactics. The result is that audiences switch in their millions and incumbents are left in tatters. Any old business that relies on scarcity economics will be swept away.
