Actually, The Osmond Brothers were discovered by Disneyland in 1962, followed by their famous TV appearance on the Andy Williams Show.
The Jackson 5 wasn't formed until 1964, and didn't make their first single record until 1967, and then joined Motown in 1969.
It seems like The Jackson 5 was the black Osmond Brothers.

the J5 were a more talented Osmond Brothers.
