the album's success was largely based on the second single released from the album, "shake your body (down to the ground)", which became a top 10 single in the spring of 1979. the album eventually peaked at number eleven on the "billboard" pop albums chart and number three on the "billboard" black albums chart and went on to platinum status-cementing it as the first riaa-certified platinum seller by the jacksons as most of their motown recordings were uncertifiable despite their huge success on the charts, and over two million copies worldwide. the accompanying tour was a huge success running on many legs and also toured overseas.
