MTV2 is an American digital cable and satellite television channel that is owned by Viacom Music and Entertainment Group, a unit of the Viacom Media Networks division of Viacom. The channel also broadcasts over-the-air in selected markets where the former all-request music channel known as The Box was broadcast (which was acquired by MTV Networks in 2001 for the sole purpose of conversion to MTV2), though these stations have been sold off in recent years, and MTV2 is no longer broadcast over the air and is now only available by cable.
