My boy and his sister did not know anything about Ben10. However, all of his classmates including his sister's classmates know about Ben10. He is 6 and his sister 8. That is because we do not subscribe to the pay tv which has a regular Ben10 show playing.
So since all his classmates are talking about Ben10, we got him a Ben 10 shoe for Chinese New Year. We also got him one or two Ben10 VCDs to watch. Then he started to ask to play Ben10 games on the computer. So we found him this link which offers online Ben10 games for free.
There are several Ben10 games with titles like Ben10 Cavern Run, Ben10 Underworld, Ben10 to the Rescue, Ben10 Power Splash, Ben10 Blockade Blitz, Ben10 Savage Pursuit, Ben10 Omnitrix Unleashed and Ben10 Forever Defense.
Since then, the kids are hooked on Ben10. Even his sister likes the Ben10 games. Their favourite is Ben10 Blockade Blitz.
How easy it is to market to little kids. It must be a multimillion dollar business indeed.
