Confusing Infobox
The infobox says the "Launch date" was April, 1921. However, it says the "First air date" was 	April 1979.

Exactly what is the difference between the "Launch date" and the "First air date"? If they are essentially the same thing, then the infobox is contradicting itself. Can anyone clarify? Thanks. 174.124.40.157 (talk) 06:58, 6 October 2011 (UTC)
