In 1959, Harold Geneen became CEO. Using leveraged buyouts, he turned the minor acquisitions of the 1950s into major growth during the 1960s. In 1965, ITT attempted to purchase the ABC television network for $700 million. The deal was halted by federal antitrust regulators who feared ITT was growing too large. In order to continue growing while not running afoul of antitrust legislation, it moved to acquire companies outside of the telecommunications industry. Under Geneen, ITT bought over 300 companies in the 1960s, including some hostile takeovers. The deals included well-known businesses like the Sheraton Hotel chain, Wonder Bread maker Continental Baking, Rayonier, and Avis Rent-a-Car. ITT also absorbed smaller operations in auto parts, energy, books, semiconductors and cosmetics. In 1966, ITT acquired Educational Services, Inc., an operator of for-profit schools, which became ITT/ESI. When ITT attempted to acquire The Hartford insurance company in 1970, the US Justice Department filed suit, and ITT agreed to divest assets equal to those of Hartford's, including Avis.
