Are Gamers a Groundbreaking form of Entertainer/Entertainment?

With the rise of many YouTube gaming personalities such as PewDiePie, Markiplier and Jacksepticeye, the idea of not have to personally purchase a game appeals to millions of people. Sitting down and watching someone else play a game, for many, is an ideal way to see what the current gaming scene is like, and a way to keep themselves occupied and entertained. My question is, are gamers a groundbreaking new form of entertainment as a new set of entertainers? They contrast with in-person comedians and live shows in that their work can be replayed and still be exactly the same, but this form of entertainment is different than the traditional idea. Are these gamers the new face of entertainment?
