July 28, 1989: The Michael Jackson California Raisin advertisement airs in theatres.
The height of Michael mania around the Bad album and Bad World tour coincided with an advertising campaign of singing raisins, singing their version of the Marvin Gaye classic "I Heard It Through the Grapevine". One of the most well known special guest characters was of course the most adorable King of Pop Michael Jackson! The singing voice is not Michael's due to some contract issues but the talking voice at the end is his.
The characters were modeled in clay and were an excellent quality advert for the time. And accordingly, sales of raisins soared.
This particular advertisemnt featuring Michael was launched in July 1989. In the advert, we see Michael's trademarks of fedora and white glove, and of course, his dance moves.
I also read that Michael received $25,000 for his contribution to the ads, which he all donated to charity.
