The Caterpillar Tractor Company was formed in 1925 when the Holt Manufacturing Company merged with the C. L. Best Tractor Company, and started producing tracked industrial and agricultural machinery in California. The first Caterpillar diesel engine was the DD9900, developed in 1930 and made famous in the revolutionary Caterpillar Diesel 60 tractor. In addition to growing product sales, much of Caterpillar's development has been due to its acquisition of other companies in related industries. Caterpillar vehicles and machinery are easily recognized around the world by the trademark Caterpillar Yellow livery and CAT logo.
