1967 Teen Titans, the first Teen Titans Cartoon

Loving sidekicks so much DC created the Teen Titans in 1964 and gave them their own run starting in 1966 and used the 1967 3 episode mini-series to promote the comic. George Kashdan, who was an Editor at DC, wrote the show. Looking back it's odd that Speedy and Wonder Girl got to be in a cartoon before Green Arrow and Wonder Woman. They first showed up in Superfriends.
In my opinion Young Justice did a better job at adapting the spirit of the early run of Teen Titans but the first Teen Titans cartoon had a better cast by far.
