Addendum:  Several people have asked me to substantiate the claim that this was the first clock radio.  I can't do that but I can tell you that it was introduced in November, 1945 and no one's yet shown me one older.  Bulova, on their website, claims to have created the first clock radio but this is the same company that claims to have invented the electric clock.... in 1931!.... and sold clocks with Hammond movements!
