Most of the early Jackson 5 singles were written and produced by The Corporation, who crafted for The Jackson 5 a sound that mixed the traditional "Motown Sound" with teenage-honed lyrics that they termed "bubblegum soul". The Jackson 5 became an instant sensation, with "I Want You Back" and its 1970 follow-ups "ABC", "The Love You Save," and "I'll Be There" all going to #1 on both the Billboard Pop Singles chart and the Billboard Soul Singles (R&B) chart. Other early Top 5 hits included "Mama's Pearl" and "Never Can Say Goodbye."

Now successful, Joseph was finally able to arrange to move Katherine and the rest of the family out to California in 1970. First moving into a two-story residence at 1616 Queens Road in Los Angeles, the Jackson family moved to a gated mansion they called "Hayvenhurst", which was purchased by Joseph in March 1971.

"Jacksonmania" swept the nation, and within a year of their debut The Jackson 5 were among the biggest names in popular music. The group essentially replaced The Supremes as Motown's main marketing focus, and, capitalizing upon the youth-oriented appeal of the Jackson brothers, Motown licensed dozens of Jackson 5-related juvenile products, including the now famous J5 Heart logo which appears on Johnny Jacksons drum kit and many of The Jackson 5's album covers, stickers, sewable patches, posters, and coloring books. A new teen magazine aimed at African-American youth, Right On!, began publication in 1971, and focused heavily on The Jackson 5; at least one Jackson adorned the cover of every issue published between January 1972 and April 1974. Animation producers Rankin/Bass produced The Jackson 5ive, a Saturday morning cartoon that debuted on September 11, 1971 and ran for two seasons on ABC. The Jackson 5 starred in two of their own television specials, Goin' Back to Indiana (aired September 16, 1971) and The Jackson 5 Show (aired November 5, 1972).

Motown began a spin-off solo career for Michael, whose first single, "Got to Be There," was a Top 5 hit. Michael also sang the title track for the 1972 motion picture Ben. His other successful solo singles included "Rockin' Robin" and "I Wanna Be Where You Are" (both 1972). Jermaine started a solo career of his own in 1972, and had a Top Ten hit with his Shep and the Limelites cover "Daddy's Home". Jackie also recorded a solo album, but his releases failed to chart. Despite fan rumors that all three Jacksons might leave the group as they released solo work, the solo careers of Michael, Jermaine, and Jackie co-existed alongside that of the group as a whole, allowing Motown to expand the success and sales of Jackson 5-related releases.
