In the business world, different types of mergers and acquisitions are defined by the similarities or differences in the products and services of the companies involved. A conglomerate merger is one that takes places between two or more companies that engage in unrelated businesses. Conglomerate mergers were common in the United States during the late 1960s and early 1970s -- partly due to antitrust laws at the time that restricted other kinds of mergers -- then became less common as most failed to deliver promised value to shareholders.

ITT, Avis Rent-a-Car, Sheraton Hotels and Continental Baking

Avis Acquires Zipcar For $500 Million

Founded in 1920 with a focus on multinational telephone service, International Telephone & Telegraph Corp. merged with several unrelated businesses to become a huge conglomerate. Although ITT had acquired several related telecommunication companies previously, in 1959 the company began the acquisition of unrelated enterprises. For example, car rental company Avis Inc., hotel chain Sheraton Corp. of America and Continental Baking Co., makes of Wonder Bread, were three unrelated companies that ITT acquired.

In 1970, Phillip Morris purchased Miller Brewing Co. This conglomerate merger united a major tobacco company, known for the popular cigarette brands Marlboro and Virginia Slims, with a major company in the beer industry, known for the Miller family of beers. In 1985, Phillip Morris Cos. acquired General Foods Corp. and, three years later, Kraft Foods. Since the mergers, the Altria Group Inc., Phillip Morris' company name since 2003, has divested these previous acquisitions.
