Michael Jackson was known as the "King of Pop" but was also pioneering in the music video genre. His early videos with the Jackson 5 lacked sophistication but videos for songs like "Rock With You" and "Billie Jean" told stories through carefully planned shots, lighting, and choreography. His "Thriller" video, costing $500,000, became the best-selling music video ever with its elaborate extended version and cultural impact. As technology advanced, Jackson's videos grew more sophisticated, using their visuals and choreography to spread messages of unity and social issues.
