How many people back in 2003 honestly knew who the Teen Titans were or that it was a comic? I sure didn't, and I imagine most people didn't either. I remember seeing the original adverts on CN and they always emphasized Robin the most...and I realize its because he was the only familiar character to the general public. Now I know Dick Grayson is a founding member of the Titans in the comics, but the cartoons always change things up (heck he was Nightwing when he was with the Titans in the comics, not Robin), so it makes you wonder...would the original TT have been a success without Robin? If say Speedy was the leader and Robin wasn't in the show, and it was 5 unfamiliar characters to the general public, would it have worked? I believe this is the same reason Robin was even in Young Justice. At the time most people were unfamiliar with Superboy, Miss Martian, we had a new Aqualad, a new character in Artemis, and Kid Flash was only recognizable because he was Wally. But Robin being there was like one familiar character around. Do they purposely include Robin in these shows simply because the network believes that he was the reason that initially drew people into them? I'm curious if the original Teen Titans would have ever worked if Robin was not with them.
