"Fortnite Battle Royale" has also become a cultural online phenomenon, with several celebrities reporting they play the game, and athletes using "Fortnite" emotes as victory celebrations. A notable streaming event in March 2018, with streamer Ninja playing "Fortnite Battle Royale" alongside Drake, Travis Scott, Kim DotCom, and Pittsburgh Steelers wide receiver JuJu Smith-Schuster, broke viewership records for Twitch to date, and led to Epic arranging a "Fortnite Battle Royale" pro–am with 50 pairs of streamers and professional players matched with celebrities at the Electronic Entertainment Expo 2018 in June 2018. Epic Games is working to develop organized eSports competitions around "Fortnite Battle Royale", including a "Fortnite" World Cup tournament in 2019.

Near the same time that Epic released "Fortnite" into early access, "PlayerUnknown's Battlegrounds" had become a worldwide phenomenon, having sold over 5 million copies three months from its March 2017 release, and drawing strong interest in the battle royale genre. Epic recognized that with the "Fortnite" base game, they could also do a battle royale mode, and rapidly developed their own version atop "Fortnite" in about two months. By September 2017, Epic was ready to release this as a second mode from "Save the World" in the paid-for earlier access, but then later decided to release it as a free game, "Fortnite Battle Royale", supported with microtransactions. This version quickly gained players, with over 10 million players during its first two weeks of release, and leading Epic to create separate teams to continue the "Fortnite Battle Royale" development apart from the "Save the World" mode, outside of common engine elements and art assets. This allowed "Fortnite Battle Royale" to expand to other platforms otherwise not supported by the "Save the World" mode, including iOS and Android mobile devices and the Nintendo Switch.
