Why did Bradbury develop the Ray Bradbury Theater?

The Ray Bradbury Theater is an anthology series that ran for two seasons on HBO from 1985 to 1986, and four additional seasons on USA Network from 1988 to 1992. It was later shown in reruns on the Sci Fi Channel and later Retro Television Network. It currently airs on Comet. All 65 episodes were written by Ray Bradbury, based on short stories or novels he wrote, including "A Sound of Thunder", "Marionettes, Inc.", "Banshee", "The Playground", "Mars is Heaven", "Usher II", "The Jar", "The Long Rain", "The Veldt", "The Small Assassin", "The Pedestrian", "The Fruit at the Bottom of the Bowl", "Here There Be Tygers", "The Toynbee Convector", and "Sun and Shadow".

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
