From 1912 to 1919 he was managing editor of The Bellman, a Minneapolis literary magazine, vice president of the Bellman Company, and a director of the Miller Publishing Company; from 1914 to 1925 he was managing editor of The Northwestern Miller. He also worked for the Minnesota Orchestra, in 1921–23 was music critic for the Minneapolis Daily News, and in 1925 was the manager of WCCO, one of the top radio stations in the country. He was also a major in the Minnesota Home Guard during World War I.
In 1927 Bellows was appointed as one of the first members of the Federal Radio Commission, predecessor of the Federal Communications Commission. He was technical adviser to the first International Radio Telegraph Conference that year. To forestall greater government interference in broadcasting, he advocated stations' programming individually to meet their listeners' needs; he left the FRC 18 months into his three-year term. From 1928 to 1935, he was a director of the National Association of Broadcasters; he was manager of Northwestern Broadcasting from 1929 to 1934 and a vice president of the Columbia Broadcasting System, forerunner of CBS, from 1930 to 1934. In 1930 he set up a transatlantic exchange for radio programs. His final position was as director of public relations for General Mills, where he founded the department.
He married Mary Sanger, the daughter of Harvard chemistry professor Charles Robert Sanger, in 1911; they had two children. After her death in 1935, he married a second time in 1936 to Alice Eels.
