The yellow smiley face is a pretty classic pre-internet meme I reckon. I was reading an interview with the CEO of The Smiley Company the other day. There is literally a company that owns the rights to the Smiley image and they turn over £280m a year just from the royalties/licenses. How crazy is that!? :p
maybe i will write part 2 :D i myself have remembered a couple of other memes...stay tuned :D
