Originally scheduled to broadcast on September 13, 2001, it was postponed due to the terrorist attacks on The World Trade Center and The Pentagon on September 11, 2001. MTV suspended all of its programming, along with its sister cable channel VH1, and it began simulcasting coverage from CBS News (the news division of CBS, which was acquired by MTV parent Viacom two years earlier) until about 11:00 p.m. ET the night of September 11. The channels then played a looped set of music videos without commercial interruption until an MTV News special edition of Total Request Live aired on September 14, 2001.
