Apex Legends is a really good game that seemed to come out of nowhere: One minute we're speculating about a Titanfall battle royale, and the next it draws 2.5 million players in its very first day. There was a quiet but concerted marketing effort in place to make that happen, which included sponsorships of streamers like Ninja, who spent hours playing the game on its launch day. According to Reuters, he was paid $1 million for his time.

The promotional relationship wasn't a secret—his stream was labeled as an "Apex Legends partner"—but the amount involved is staggering, particularly given that the report suggests that it was solely for launch day. An Electronic Arts rep seemed to confirm that, telling Kotaku that its marketing campaign included "paid engagements with some content creators at the launch of the game," and that after February 5, "all Apex Legends streaming from content creators was completely organic."
