IBM

International Business Machines (IBM) is the world's top provider of computer products and services. Among the leaders in almost every market in which it competes, the company focuses primarily on its growing services business, which accounts for more than half of sales. While IBM made its name in computer hardware, the company's information technology, business services, and software units are now among the largest in the world. The company is also one of the largest providers of semiconductors, and its computing hardware legacy lives on in the form of its industry-leading enterprise server and data storage products lines.
