Chandler built the Los Angeles Times into arguably the most powerful and successful newspaper on the West Coast. Chandler so greatly expanded the reach of the Times that by 1941 the paper had a daily circulation of 320,000 with 615,000 on Sundays. For three straight years in the 1920s, Chandler’s Times led all other American newspapers in advertising space and amount of classified ads. Under Chandler’s leadership, the Times was also the first newspaper in the country to establish a personnel department, and one of the first to adopt the forty hour work week.
