[BC] One More Telephone Query

[Donna Halper]

So, we've established that the technology for putting phone callers 
on the air DID exist, even in the 1920s and 30s; and yet in the late 
40s, talk hosts were still using paraphrase-- Ed and Wendy King of 
KDKA in Pittsburgh and the late shock jock Joe Pyne, to give several 
examples.  The talk host would repeat what the callers had said, 
rather than letting the callers' voice be heard on the air.  Is there 
a reason they did it that way?  Lack of a seven second delay perhaps?
