Maybe we're defining "killer app" differently, but over 80% of US households had a radio in 1940, a decade prior to the start of rock and roll.
I think of "killer app" to be something that drives the adoption of the platform or whatever. "Why should I buy a PC? Oh, because Lotus 1-2-3 is awesome." Nobody was buying radios because they wanted to listen to rock and roll music; they all already had radios.
