This has been a mystery to me for quite a while. I'm talking about this cup:
The screenshot is from the 2008s movie Fanboys. The exact same cup also appears in movies such as:
American Pie (screenshot is from nr 2):
Blue Mountain State (screenshot is from episode 5 season 1):
Easy A (same style cup, just blue instead of red)
Other examples include No Strings Attached, The Spectacular Now, 21/22 Jump Street and probably a lot more.
Why is it always the same type of beer cup used in these college-style movies/series? Is it part of a cleaver product-placement plan or is it just the only suitable cup available in the US?
