Bronycon 2015 was the year Bronycon made history by becoming the first brony convention to reach over 10,000 attendees with 10,011 people in attendance. It was also the year the "Good Morning Baltimare" parody song and animation was released, the song that would be played to start every Bronycon in the future.
