Tech Giant Apple is an example of more concentrated ownership (or vertical integration)

Explanation:

Vertical integration refers to expansion of business in a way that no outside entity or service is required in the entire process of manufacturing and distribution.  

For instance – Tech Giant Apple has its own retails store, has its own brand and manufacturing facilities around the globe. Thus, they do not need an outsider for carrying out these activities.
