larger plant and later made subsequent expansions. The Crosley Radio Corporation became the largest radio manufacturer in the world in 1925; its slogan, "You’re There With A Crosley," was used in all its advertising. In 1925 Crosley introduced another low-cost radio set. The small, one-tube, regenerative radio was called the "Crosley Pup" and sold for $9.75. While Victor had Nipper, its famous trademark showing a dog listening to "his master's voice" from a phonograph, Crosley adopted a mascot in the form of a dog with headphones listening to a Crosley Pup radio In 1928 Crosley's firm arranged for the construction of the Crosley Building at Camp Washington, a Cincinnati neighborhood, and used the facility for its for radio manufacturing, radio broadcasting, and for manufacturing other devices. In 1930 Crosley was marketing the "Roamio," with "screen grid neutrodyne power speaker" for automotive use. Priced at $75, before accessories and installation, it was claimed to be able to receive thirty stations with no signal strength change. Radio broadcasting Once Crosley established himself as a radio manufacturer, he decided to expand into broadcasting as a way to encourage consumers to purchase more radios. In 1921, soon after he built his first radios, Crosley began experimental broadcasts from his home with a 20-watt transmitter using the call sign 8CR. On March 22, 1922, the Crosley Broadcasting Corporation received a commercial license to operate as WLW at 50 watts. Dorman D. Israel, a young radio engineer from the University of Cincinnati, designed and built the station's first two radio transmitters (at 100 and 1,000 watts). The Crosley Corporation claimed that in 1928 WLW became the first 50-kilowatt commercial station in the United States with a regular broadcasting schedule. In 1934 Crosley put a 500-kilowatt transmitter on the air, making WLW the station with the world's most powerful radio transmitter for the next five years. (On occasion, the station's power was boosted as high as 700,000 watts.) Throughout the 1930s, Cincinnati's WLW was considered "the Nation's Station," producing many hours of network programming each week. Among the entertainers who performed live from WLW's studios were Red Skelton, Doris Day, Jane Froman, Fats Waller, Rosemary Clooney, and the Mills Brothers. In 1939 the Federal Communications Commission (FCC) ruled that WLW had to reduce its power to 50 kilowatts, partly because it interfered with the broadcasts of other stations, but largely due to its smaller competitors, who complained
