Which investment company has been led by Warren Buffett as chairman and CEO since 1965?

Berkshire Hathaway has been led by Warren Buffett as chairman and CEO since 1965.

Buffett began buying shares in the struggling textile company Berkshire Hathaway in the early 1960s. After taking control, he shifted the business away from textiles and toward insurance, investments, and ownership of operating companies.

Berkshire’s subsidiaries and investments have included GEICO, BNSF Railway, Berkshire Hathaway Energy, and large stakes in major public companies. Its wide collection of businesses and valuable investment portfolio have made it one of the world’s most prominent corporations.

Berkshire Hathaway is not a conventional technology company, even though it has ranked among the world’s most valuable public companies. Its market value reflects decades of retained earnings, insurance operations, wholly owned businesses, and investment performance.
