Conglomeration
When a business grows through unrelated diversification, acquiring companies in different industries, it is called a conglomeration.
A conglomerate is a corporation made up of a number of different, unrelated businesses. In a conglomerate, one company owns a controlling stake in a number of smaller companies which conduct business separately.
A good example is Warren Buffet’s Berkshire Hathaway, that has a very thriving conglomerate that has successfully managed companies involved in everything from plane manufacturing to real estate, is widely respected and is one of the most well-known companies in the world.
