The Black & Decker Company was founded by Alonzo Decker and Duncan Black in 1910 in Baltimore, Maryland. The company started producing power tools in 1916, and through an aggressive sales strategy, acquisitions, and a widened product offering, became the leading power tool maker by the 1950s. In 1960, the company purchased Dewalt, a leading player in high-end power tools today.
The company underwent significant stagnation from the late 1990s to the early 2000s. The company was eventually merged with Stanley Works in 2010 to form the Stanley Black & Decker company (SWK). The sales of the combined company totaled $11.1 billion in 2015. Its major competitors in the North American region are Illinois Tool Works (ITW), Snap-on (SNA), and Tyco International (TYC).
