Years ago I listened in on a teleseminar where the topic was Continuity programs. I barely knew what they were and had only a slight reference to how they might be applicable to what I do as an author and speaker.
Oddly enough, I had subscribed to a famous author educational program, paying $80 to receive an hour long audio program once a month. But I had no idea it was called a continuity program.
Most people are probably more familiar with the cooking clubs which send out a beautifully designed binder which is free, but the monthly recipes might cost anywhere from $9.95 to $19.95. That is probably the original concept where continuity programs actually began.
