Rock Band

Rock Band is a series of music video games developed by Harmonix and MTV Games, and distributed by Electronic Arts for the Nintendo DS, iOS, PlayStation 2, PlayStation 3, PSP, Wii, and Xbox 360 game systems. The series, inspired by Harmonix's previous efforts on the Guitar Hero series, allows up to four players to simulate the performance of popular rock music songs by playing with controllers modeled after musical instruments. Players can play the lead guitar, bass guitar, keyboard, and drums parts to songs, as well as sing into a USB microphone. Players are scored on their ability to match scrolling musical notes while playing instruments, and by their ability to match the singer's pitch on vocals.

The concept for Rock Band was formed while Harmonix was working on the Guitar Hero series, with the idea to expand the note-matching gameplay into multiple instruments. When their Guitar Hero partner, RedOctane, was acquired by Activision, Harmonix was acquired by MTV Games, a division of Viacom, allowing them to pursue the title. The first game in the series, Rock Band, was released in 2007 and its sequel Rock Band 2 was released in 2008. As the rhythm game market began to flounder in 2009, Viacom put Harmonix up for sale, but investors were able to buy the company, making it an independent studio. Harmonix would go on to expand the series, including obtaining the lucrative licensing needed for The Beatles: Rock Band in 2009. Rock Band 3 was released in 2010 which introduced new "Pro" features and keyboard parts. Following saturation of the rhythm game market, Harmonix opted to wait on releasing another main title for several years. Upon the release of the next generation of consoles, the PlayStation 4 and Xbox One, Harmonix released Rock Band 4 in October 6, 2015; the company does not plan to release further versions of the game for these consoles but instead see Rock Band 4 as a platform they can continue to expand on through game patches.
