MCA, Inc. (or Music Corporation of America) was an American talent agency. Initially starting in the music business, they would next become a dominant force in the film business, and later expanded into the television business. MCA published music, booked acts, ran a record company, represented film, television and radio stars, and eventually produced and sold television programs to the three major television networks.

MCA was founded in 1924 by Jules Stein and William R. Goodheart, Jr. as Music Corporation of America, a music booking agency based in Chicago, Illinois. MCA helped pioneer modern practices of touring bands and name acts. Early on, MCA booked such prominent artists as King Oliver and Jelly Roll Morton for clubs and speakeasies run by legendary notorious Chicago mobsters such as Al Capone and others.

Lew Wasserman joined MCA in 1936 at the age of 23 and rose through the ranks to MCA for more than four decades, with Sonny Werblin as his right-hand man. Wasserman helped create MCA's radio show Kay Kyser and His Kollege of Musical Knowledge, which debuted on NBC Radio that same year. Following that success, Stein installed Wasserman in New York City in 1937, but Wasserman convinced him that Hollywood was the best place for the company's growth.

Ben Pollack (June 22, 1903 - June 7, 1971) was an American drummer and bandleader from the mid 1920s through the swing era. His eye for talent led him to either discover or employ, at one time or another, musicians such as Benny Goodman, Jack Teagarden, Glenn Miller, Jimmy McPartland and Harry James. This ability earned him the nickname "Father of Swing".

Born in Chicago in 1903 to a well-to-do family, Pollack was largely self taught as a drummer, and was afforded the opportunity to become the drummer for the New Orleans Rhythm Kings, a top jazz outfit, in the early 1920s. In 1924 he played for several outfits, including some on the west coast, which ultimately led to his forming a band there in 1925. One of the earliest members of his band was Gil Rodin, a saxophonist whose sharp business acumen served him well later as an executive for the Music Corporation of America (MCA). Rodin also served as the "straw boss' for Pollack along with the young arranger-trombonist Glenn Miller. Already recognized as immensely talented on the clarinet, sixteen-year-old Benny Goodman began working with Pollack in 1925 as well.

Mariah Carey (born March 27, 1970) is an American singer, songwriter, record producer, and actress. She made her recording debut in 1990 under the guidance of Columbia Records executive Tommy Mottola, and released her self-titled debut studio album, Mariah Carey. The album went multi-platinum and spawned four consecutive number one singles, on the U.S. Billboard Hot 100 chart. Following her marriage to Mottola in 1993, a series of hit records, including Emotions (1991), Music Box (1993) and Merry Christmas (1994), established her position as Columbia's highest-selling act. Daydream (1995), made music history when the second single, "One Sweet Day" a duet with Boyz II Men, spent a record sixteen weeks on top of the Billboard Hot 100, and remains the longest running number one song in US chart history. During the recording of the album Carey began to deviate from her pop background, and slowly traversed into R&B and Hip-hop. After her separation from Mottola, this musical change was evident with the release of Butterfly (1997).
