The Hearsts

Similarities: All of William Randolph Hearst's five sons followed the newspaper mogul into the family business. (He's pictured left with his infant son William Jr. in 1908.)

Differences: The family-owned Hearst corporation, which owns more than 360 businesses (including Town & Country), was established on March 4, 1887, when William Randolph Hearst put his name on the masthead of the San Francisco Examiner. The company has been passed down through three generations, and his grandson William Randolph Hearst III is now its chairman.
