The Fox show 24 had my all-time favorite negative product placement.
Ford was a huge sponsor for 24 for many seasons. All of the CTU agents drove Expeditions and Excursions.
But then at one point, Agent Almeida’s girlfriend is kidnapped by the terrorists and he’s forced to work for the badguys. He goes to the CTU parking lot, and gets in the ONE AND ONLY CHEVY SUBURBAN IN THE CTU FLEET and takes off to help the badguys.
I thought it was absolutely hilarious.
