BK was also a leader in cross-promotion. In 1977, they ran commercials using Star Wars advertising while selling glasses with the characters from the film.
Movie studios have been using paid promotions for products since the 90s. Iirc the very first paid movie tie-in was in ET. The studio had planned on using M&Ms in the film but were rejected by Mars. Hershey’s heard about this and paid them to instead use Reese’s Pieces in the movie.
It’s fair to hate it, I usually do, but it happens all the time. The only one I can think of that I liked was 30 Rock, especially with their Snapple product placement.
