(June.) In speaking of television for the past 25 years or so, we have been accustomed to saying that "televi- sion is around the comer." I should like to bury that phrase. Television is no longer around the comer. It is beyond the doorstep; it has pushed its way through the door into the home! — David Sarnoff, September 13, 19i7. Louis-Walcott Telecast Sets All-Time Record Approximately seven out of every eight television receivers in the seven cities served by the NBC Television network, were in use on the night of June 25, and 99.7% of the sets were tuned to the Louis- Walcott championship prize fight that evening, a special survey by C. E. Hooper, Inc., revealed. The resulting rating of 86.6—highest in the history of radio and televi- sion—was 7.6 points above the broadcast of President Roosevelt's war message on December 9, 1941, the previous record holder. Further analysis of the survey showed that the total television audience of WNBT, New York, key station of the NBC network, was 3,930,000 with two million addi- tional viewers distributed among the remaining cities carrying the network sports feature. WNBT's average home audience was 12: seven men, four women and one child. Electron Microscope for Virus Research Impressed with the fact that the effective treatment of colds is pos- sible only by an understanding of the cold virus of which he was a victim, Earling H. Samuelsen, Nor- wegian ship owner, has donated an RCA electron microscope to the In- stitute of Bacteriology of the Uni- versity of Oslo for use in conducting research in the virus infections com- mon to Norway. The idea of the gift was conceived by the donor while he was being treated with a series of cold injections by Dr. Theodor Thjotta, Director of the Institute and Professor of Bac- teriology. The RCA electron microscope per- mits the examination of bacteria, viruses and other particles of the submicroscopic world, with mag- nifications up to 100,000 diameters.
