If it's that easy to miss then the culture has comparatively died. Memes are still around, but there was a period where they were everywhere. Like the gas station would have a bad luck Brian meme if the bathroom was out of order. You walked in Kohls and there were three different variations of "Know Your Meme" type games on an end cap. The average person would see and hear multiple memes daily in the course of everyday non-internet related activities, then they fell way off. 6-7 was the meme culture dead cat bounce.
