Berkshire Hathaway’s journey began in the textile industry in the 1830s. Originally named the Valley Falls Company, the firm produced textiles and operated mills in New England. However, in the 1950s, technological advancements and competitive pressures rendered the textile industry increasingly unprofitable. Recognizing the need to pivot, Berkshire Hathaway became an investment holding company under Warren Buffett’s leadership.

Under Buffett’s guidance, the company diversified its holdings and gradually exited the textile industry. This strategic shift marked Berkshire Hathaway’s transformation from a struggling textile manufacturer into a conglomerate spanning industries.
