X People Missed the Like Button is a type of comment usually found on YouTube, in which the "x" represents the number of dislikes the video has accumulated at the time of the commenter's viewing. The phrase can also be modified to take on a biased tone as to criticize the viewers who chose to dislike the video.
The comments regarding the like-to-dislike ratio of YouTube videos began to emerge sometime in January 2010, following the opt-in launch of YouTube's new layout which replaced its old five-star rating system with a binary upvoting / downvoting option. The decision came a few months after YouTube's official report published in September 2009, which found that most videos were given one or five stars based on its old rating system.
This new layout rolled out to all users at the end of March 2010, resulting in many users complaining about the new system on the official YouTube help forum and the Escapist forums. While the earliest instance of these comments is hard to ascertain, the first question about this type of comment was submitted to Yahoo!
