Spreading idea or image (4)

I believe the answer is:

meme

(Other definitions for meme that I've seen before include "online phenomenon" , "Transmitted cultural idea" , "Concept that spreads rapidly on the Internet" , "Cultural feature passed on by imitation" , "Often trite image" .)

I've seen this clue in The Times.
