He didn't even have to leave his house.

As live concerts went out the window this year, a number of artists came up with ways to continue performing for audiences.

Sophie Ellis-Bextor is having discos in her kitchen, Dua Lipa hosted a series of concerts in 'Studio 2054', breaking all kinds of livestreaming records in the process. Travis Scott, on the other hand, did a 10-minute appearance on 'Fortnite' and bagged $20 million for the trouble.

Scott appeared on the game's open-world in April of this year in a much-hyped "virtual concert", which saw nearly 12 million viewers take part. The whole thing lasted all of maybe nine, ten minutes, but it was enough to land Scott a nice payday and set up 'Fortnite' for live events in the future.

Here's the event in question.

The figures, quoted by Forbes, haven't yet been confirmed by Epic Games, but given the number of viewers versus what Scott normally earns for a live concert, they're probably accurate. In 2018, Scott earned around $53 million from 'AstroWorld' tour, which saw him take in 56 shows across nearly four months of steady touring.

In fact, the outcome of the success with 'Fortnite' is that Scott is now apparently working with Sony as a "strategic creative partner" on the PlayStation 5 brand, which will probably mean a limited edition Travis Scott PS5 console in the near future.

Other musical acts have tried the 'Fortnite' route, with K-pop band BTS debuting a music video in September of this year, while J Balvin hosted an 'Afterlife Party' on the game just last month. Epic Games' strategy seems to be moving 'Fortnite' away from just being a game and into something akin to a social network, and given how much money the likes of Facebook and Twitter makes, it could be a winning strategy.
