moderate its investigative reporting, E. W. Scripps founded the Chicago Day Book in 1911 as an experimental daily paper entirely devoid of advertising. The Day Book folded in 1917. In 1924, the Post was the only Cincinnati daily that endorsed a new municipal charter based on the council–manager system, nonpartisan elections, and proportional representation. The enactment of this charter the following year propelled the Charter Committee to power and led to the demise of political machines in Cincinnati, ultimately dooming the Cincinnati Subway that was seen as a product of bossism. In 1936, the Post backed the nonpartisan movement as it expanded to the Hamilton County government. In 1947, the Post successfully defended the proportional representation system against a campaign by Charles P. Taft to repeal it. Consolidation On October 1, 1935, the Post's corporate parent, Scripps-Howard Newspapers, entered the radio business by purchasing AM station WFBE 1230. The callsign was changed to WCPO, for "The Voice of the Cincinnati Post", and the station switched to a news radio format. Initially, the station's main studios were located in David Sinton's hotel, while news bulletins originated from a broom closet adjacent to the Post city room. WCPO-TV signed on the air on July 26, 1949. By the late 1940s, sales of The Cincinnati Enquirer, Cincinnati's remaining morning daily, had increased dramatically, fueled in part by the success of its Sunday morning monopoly; meanwhile, the Post and especially The Cincinnati Times-Star faced a declining afternoon market. In 1948 and 1949, lawyers for Scripps-Howard and The Times-Star Company discussed the possibility of jointly publishing a Sunday morning edition called the Times-Post. The two companies determined that they would be safe from Sherman Act investigations, which were rare in the newspaper industry; however, they eventually scrapped the idea for fear that the Enquirer would sue them for any losses. Another factor was the difficulty of establishing a Sunday carrier system. On April 26, 1956, Scripps-Howard purchased a 36.5% controlling interest in the Enquirer for $4,059,000, beating out The Times-Star Company's $2,380,051 and Tribune Publishing's $15 per share, or $2,238,000. Then, on July 20, 1958, Scripps also acquired the Times-Star, merging the afternoon paper with the Post. Only three Times-Star reporters were retained. The combined paper operated out of the Cincinnati Times-Star Building, noted for its Art Deco architecture. The paper would be published under the name The Cincinnati Post and Times-Star until December 31,
