30 years ago, Lego's were a bunch of blocks. The "new" Lego were individual sloped parts for roofs or a window block. Today, Lego sets are a theme or model. Does this increase engagement? How does it increase repeat sales by have avid Lego consumers buy the latest and greatest Lego model?
So now, how does that relate to other business models? Imagine a construction business and how it is totally different. Lego has figured out how to scale their business to a multi-million dollar business. Look at a garage floor coatings
business that is limited to a regional area. By contrast, Lego wins hands down.
