Anyone who’s owned one of these magnificant systems will admit to the curse of the near-instantaneous consumption of batteries. Energizer naturally used a boombox to poise itself as the battery brand of choice for these systems. We were ecstatic to find this commercial lodged between late night movies on an old VHS tape. While we can’t determine the make or model on this system, it’s easy to see that boomboxes had reached mass appeal in 1983 when they wind up as the center of attention in a little girl’s slumber party.
