The business model used to be a pretty universal term. The same skeleton applied to many businesses, and it involved a customer becoming aware of a product (billboard, print ad, yellow pages, etc.), speaking with the seller and thinking their purchase over for days (or weeks) after getting a quote, and (hopefully) an eventual purchase. That process could drag on and on, decreasing the likelihood of a sale with each and every passing step of the linear path.
While the way consumers go about buying has in some ways been simplified by digital marketing (i.e., fewer steps, purchasing power at the click of a button), the ways they interact with and reach businesses has multiplied. And, while competition has increased significantly among businesses, there has never been more opportunity for growth and success.
