"tried to prevent the publication of that article ... but failed in that effort"; In 1927 the Watch Tower Society ceased printing of Russell's Studies in the Scriptures. The Editorial Committee was dissolved in 1931, after which Rutherford wrote every leading article in The Watch Tower until his death. The 1933 Watch Tower Society Yearbook observed that the demise of the Editorial Committee indicated "that the Lord himself is running his organization". Rutherford expanded his means of spreading the Watch Tower message in 1924 with the start of 15-minute radio broadcasts, initially from WBBR, based on Staten Island, and eventually via a network of as many as 480 radio stations. A 1931 talk was broadcast throughout North America, Australia and France, but his attacks on the clergy resulted in both the NBC and BBC radio networks banning his broadcasts. In 1928, Rutherford began to abolish the system of electing elders by congregational voting, dismissing them as "haughty" and "lazy", and finally asserting in 1932 that electing elders was unscriptural. He impressed on elders the need to obey the Society's "regulations", "instructions" and "directions" without complaint. Service directors, who reported back to Brooklyn, were appointed in each congregation and a weekly "service meeting" introduced to meeting programs. In 1933 Rutherford claimed that abolishing elective elders was a fulfillment of the prophecy of 2300 days at Daniel 8:13–14, and that God's sanctuary (the Watch Tower Society) was thereby cleansed. At a 1931 Bible Student assembly in Columbus, Ohio, Rutherford proposed a new name for the organization, Jehovah's witnesses, to differentiate them from the proliferation of other groups that followed Russell's teachings. Bible Students who opposed or abandoned Rutherford to form new groups were increasingly described as the "evil servant class" by The Watchtower, which said it was wrong to pray for those who were "unfaithful". Four years later the term "Kingdom Hall" was introduced for the local meeting place of congregations. In 1937, the door-to-door preaching program was extended to formally include "back calls" on interested people and Witnesses were urged to start one-hour Bible studies in the homes of householders. In the late 1930s, he advocated the use of "sound cars" and portable phonographs with which talks by Rutherford were played to passersby and householders. In 1938, he introduced the term "theocracy" to describe the denomination's system of government, with Consolation explaining: "The Theocracy is at present administered by the Watch
