December, 194} Page 399 ^Ot ■E± full commercialization of television, about ten per cent of the wired homes in the foregoing cities or 741,000 families, representing a probable audience of seven million people would own television receivers. "We can assume further," he continued, "that within three (ir four years after commercial resuni])tion of television, \\'ashington, D. C, Baltimore, Hartford, Providence, and Boston will have television transmitters. These cities, together with Philadelphia, New York, Schenec- tady and Albany, could be J interconnected with a tele- vision network circuit about 600 miles long." The RCA executive then went on to describe the develop- ment of the television network by trunk lines, thus link- ing the middle west with the Atlantic seaboard. This trunk line television network, with the secondary net- works that would be off-shoots from it, he said, can be expected to develop approximately five years after the full commercialization of television. By the end of the fifth year, he said, engineers should be able to de- velop the automatic transmitter for rebroadcasting tele- vision programs, thus blanketing areas of the country imreached by the stations in the 157 key cities. Mr. Joyce also took occasion to remind his audieqce that it was too much to ex])ect television to spring for- ward as an industry the day the fighting ceases. "It may be a year, or two or three years after the war before television is ready to go forward on a commer- cial basis," he iterated. "Of this, though, we may be certain : that the generations that come after the war will take home television service just as much for granted as the present generation lakes radio." CIAA Film Program Progresses The ^Motion Picture Division of the Coordinator of Inter-American Affairs, which was inaugurated two and a half j'ears ago to promote the cultural exchange of information with the Latin American republics, to date has distributed 170 films on the U. S. to Mexico, Central and South America, according to the first niun- ber of Salndos Amigos. a newsletter which is to be issued regularly to the distributors of the Coordinator's motion pictures. These films have come from various sources—the motion picture industry, commercial and advertising film sources, the Army Signal Corps train- ing film program. Office of War Information and other Government agencies, educational institutions and pri- vate sources. Many have been produced especially for the Coordinator. 182 16mm projectors have been pro- vided for the Latin America film showings. In the United States, 48 subjects on Latin America are now available for non-theatrical exhibition, approxi- mately twice the number in circulation here a year ago. The latest of these films include Good Neighbor Family, Schools to the South. Montevideo Family, Housing in Chile and Young Uruguay (produced in South America by Julien Bryan) ; Jungle Quest and Treasure Trove of Jade (from the National Geographic Society) and the travelogues on Mexico, titled Pic- turesque Patscuaro, The Road to Cuernavaca, and Tchuantepec.
