Rainbow Six Siege official caster Yamano Tomozo published a column tracing the game's 10-year history, arguing its success came from timing with the rise of streaming and video culture rather than traditional advertising. He notes the development team started with only 25 people, which limited promotion at launch in December 2015. The game's active user count on Steam first broke 100,000 in early 2018, over two years after release, coinciding with the growth of YouTubers and streamers. Ubisoft reported cumulative players exceeded 100 million as of December 2025.
