“In October of 1958, Physicist William Higinbotham created Pong, which is thought to be the world’s first video game. Since then, video games have become part of mainstream culture, and every so often a transcendent game comes out, like Pac-Man or World of Warcraft, that brings in billions in revenue. Released in July of 2017, Fortnite may be on track to become that kind of game.
Fortnite, a cooperative survival game, ​has gone viral on a global scale in 2018. The game itself is free to download, which makes it particularly appealing, but it makes its money through in-game purchases that players have the option to buy. In fact, an April report by analytics firm Sensor Tower found that Fortnite was making an average of $1 million every single day from player spending”.
