How does one measure the strength and influence of the Forward in Faith Broadcast? It’s been on since the 1940’s, I remember when Ray Hughes and Bennie Triplett were the speakers. Loran Livingston has been the speaker since 1990. I remember hearing it in the Chicago area. The broadcast is now heard in 27 states but even so radio in general has fallen on bad times with the exception of the ” hate-talk” type programs. Actually I can’t remember even one time that the broadcast has been brought up in regular conversation. Can you? However since it is now available over the internet, with some creative thinking and a little more investment to make people aware it’s influence might be magnified. So many opportunities but the laborers are few.
