Well, it depends on what you define as the “previous” business model. To my way of looking at it, from the organizations inception until the start of the donation arrangment, it was selling books ands mags. After the donation arrangement started it limped along with less success but technology slowly morphed the world into a digital place. The org kicked and screamed until very very recently but has embraced it to the point now that there are no new releases at conventions. Everything is digital.. that marks, again from my perspective, the start of a different business model.
edited to add: bear in mind bob, i didnt say the previous model made no sense, i said it “no longer made sense.”. It worked very well until the late 80’s early 90’s. It slowly deteriorated after the whole swaggert thing forced the change to donations.
