Document 13: Michael Jackson videography: American entertainer Michael Jackson (1958–2009) debuted on the professional music scene at age five as a member of The Jackson 5 and began a solo career in 1971 while still part of the group. Jackson has been called the King of Music Videos. Steve Huey of AllMusic observed how Jackson transformed the music video into an art form and a promotional tool through complex story lines, dance routines, special effects and famous cameo appearances, simultaneously breaking down racial barriers. Before "Thriller", Jackson struggled to receive coverage on MTV, allegedly because he was African American. Pressure from CBS Records persuaded MTV to start showing "Billie Jean" and later "Beat It", leading to a lengthy partnership with Jackson, also helping other black music artists gain recognition. MTV employees deny any racism in their coverage, or pressure to change their stance. MTV maintains that they played rock music, regardless of race. The popularity of his videos on MTV helped to put the relatively young channel "on the map"; MTV's focus shifted in favor of pop and R&B. His performance on "Motown 25: Yesterday, Today, Forever" changed the scope of live stage show; "That Jackson lip-synced 'Billie Jean' is, in itself, not extraordinary, but the fact that it did not change the impact of the performance is extraordinary; whether the performance was live or lip-synced made no difference to the audience" thus creating an era in which artists re-create the spectacle of music video imagery on stage. Short films like "Thriller" largely remained unique to Jackson, while the group dance sequence in "Beat It" has frequently been imitated. The choreography in "Thriller" has become a part of global pop culture, replicated everywhere from Indian films to prisons in the Philippines. The "Thriller" short film marked an increase in scale for music videos, and has been named the most successful music video ever by the "Guinness World Records".
