Remember Blockbuster? I do as it was a staple growing up in the 90s. I also remember how every time I rented a movie; they would offer me a deal to get a box of candy or microwave popcorn along with the movie. I typically said yes, because … well, candy. This is the power of ancillary revenue in motion. Blockbuster wasn’t a candy store, but here I was purchasing candy with a movie rental.
