If you are currently looking at adopting a popular business model, whether it be for a new business idea or innovating or updating an existing business, a strong strategy would be to familiarise yourself with today's popular business models. Then adopt one (if possible) that will be widely adopted over the next 5 years. That way you can get ahead of your competition. Here is some useful information and a resource to get you started:
Business models:
A strong, precise business model(s) can be a powerful tool for innovation, competitive advantage, decision-making, and culture development.  Business models (BM) can either be explicit, written/drawn out, or implicit, unspoken/ undocumented, yet no less powerful.  A business model can be a graphic, template, or text heavy document in the form of a business plan.  Often businesses have more than one business model (BM). For example, a business may have one BM for each of the following:
Innovation
Change
Technologies
Building and developing strategic partnerships
Acquisitions
There are over 50 types of BM’s that most businesses fall into (Gassmann et al, 2014). Some of the most common today are:
Freemium (18) - use some of the service for free, upgrade for additional functionality;
Subscription (48) - pay a monthly fee starting at an affordable price point with the option to increase or decrease over time;
E-commerce (13)- sell products/services online;
Performance based (38) - the client pays on results.
