I remember that for a while in the early 00s we always saw Audis everywhere in blockbuster/action flicks, and after some while I got annoyed by those on the nose commercials. Even in sci-fi flicks like I Am Robot with Will Smith we saw futuristic Audis, and by then it just got ridiculous. And yeah, we don't have to mention those Transporter flicks. Whoa, an Audi can actually fly..
On the other hand, If you watch Psycho (1960) today and pay attention, you'll notice how much of a Ford commercial it actually is. Janet Leigh changes her older Ford for a more update Ford model at a Ford-dealer early on. All the police cars turning up later are all Fords. And so on. You rarely see any car brand besides Ford in this classic film. This is nothing new.
