One supporting data point: back when the game 2048 went viral I happened to be on a break with nothing to do, so I coded up an AI for it in one night [1]. The next day it blew up on Twitter and elsewhere. There have since been many other, better AIs, but since mine was first and came out when the game was on everyone's mind, it was the only one that got so much attention.
Someone much wiser than me once said, “dedicated people can force luck to happen”, implying that it’s only a small part of the equation.
First mover advantage ties into this here, as does discussions on the free market, and other interesting economic theory.

It can take luck to get the business off the ground though.
