A YouTube viral video entitled "Bike Hero" showed what appeared to be a teenager riding a bike along a route marked with symbols similar in appearance to the in-game note tracks with LED lights on the handlebars blinking in time to the notes to the song "Prisoner of Society" by The Living End. The video was later determined to be the work of a viral marketing company Droga5 in cooperation with Activision to promote the "Guitar Hero" games. The viral advertisement was considered a success, with about 3.5 million views since its release.
