Steam is Valve's PC gaming platform, and its toast notifications are the pop-up alerts that appear in the corner of the screen for friend activity, messages, achievements and invites. The sound became familiar to PC players through use of the client, rather than through a viral video, and editors later borrowed it to fake or parody those pop-ups in gameplay videos and streams. Like a Discord notification, it works as instant shorthand for a message arriving, which is why gaming creators still reach for it when they want a joke to feel like an in-game alert.
