What product placements were there in Seinfeld?

1) Coca-Cola and Pepsi are the obvious ones. If you watch closely, whenever someone drinks out of the can, they always make sure to face the logo to the camera. In the Gortex episode, the "I don't drink wine, I drink Pepsi" line was written-in as advertisement. If you have doubts that these were paid for by Coca-cola, just watch the scenes where characters drink milk or beer -- the carton/bottle there just says "Milk" or "Beer."

2) Saab. This could have been out of Jerry's own love for the car maker, which is well-known, but I still think Saab made sure to give him and the crew a couple free cars there.

3) Porsche posters all over the apartment in many episodes. Same thing as with Saab but more subtle.

4) Snickers. This was probably one of the most genius product placements in the 90s. Sugar Ray Lennon, George's boss, does have the logo facing the camera, but the main genius here was probably to start the trend of eating with fork and knife.

What else did you guys notice? Sorry if this is a stupid post.
