BROADCASTING

the sending abroad through the air, from central stations by wirele telephony, of news, music, lectures, weather forecasts and other matters of general interest, for, the benefit of those who are provided with receiving outfits or who gather in central places to listen. Broadcasting was taken up on a large scale following the World War, with the restrictions on the use of wirele telephony removed. This was followed by a great increase in the number of radio outfits in use in the United States. By December, 1921, this had reached nearly 250,000, and before the end. of 1922 there were well over a million outfits in general use, Broadcasting is done from central stations which are equipped with powerful apparatus and chiefly in the hands of the larger electrical corporations, including the Westing house, the General Electric, etc. This is done, chiefly to stimulate the sale of radio apparatus. Many interesting phases of broadcasting have resulted from the widespread use and simplifica~ tion of the radio. Important speeches by the President and others are broadcasted, as are concerts, sermons, and matter of any general interest. See Rapio TELEPHONY.
