Step 1 : Introduction to the question "Which fictional TV family owns a dog named Astro?"
The Jetsons was an animated sitcom produced by Hanna-Barbera originally airing in primetime from 1962 to 1963. It was the first TV show on ABC to be broadcast in color. It had a catchy theme tune and a whole bunch of wacky ideas about what 2063 would look like. Astro is the family dog and the best friend of the father, George Jetson and the son, Elroy. Astro began almost every word with a growling-type of sound that started with the letter R. He is able to speak in a rough sounding English resembling dog barks and growls, a manner of speaking which voice actor Don Messick would later reuse for the role of Scooby-Doo.
