Wenn eine solche Nachfrage weit verbreitet wäre und sie Beweise für die Personalsicherheit liefern würde, so war es offensichtlich, dass das Bell-System angesichts seiner langen Erfahrung auf dem Gebiet der Drahtglosprophonie nicht nur eine Gelegenheit, sondern eine Verpflichtung hätte, das beizutragen, was es könnte, Zur Entwicklung des Rundfunks. Es war fast ebenso offensichtlich, dass dieser Beitrag nicht nur in der directio liegen würde

. Bell telephone magazine . ELEPHONE QUARTERLY But just how general this need was, or how pronounced or howpermanent the demand for broadcasting service was to become, were questions as yet unanswered. If such a demand were tobecome widespread and if it were to give evidence of per-manency, it was apparent that the Bell System would have notonly an opportunity but an obligation to contribute what itcould, in view of its long experience in the field of wire te-lephony, to the development of radio broadcasting. It wasalmost equally apparent that this contribution would lie notonly in the direction of assisting in developing transmittingapparatus for the broadcasting stations and designing improvedreceiving apparatus, but in the equally important field of link-ing broadcasting stations with the points of origin of theirprograms and of connecting stations for simultaneous broad-casting—that is, for what later came to be known as chain ornetwork radio service. But the participation of the Bell System in any of these. The Second National Defense Day Program, July 4, 1925, Found TelephoneWires Uniting R.dio Stations from Coast to Coast. 78 NETWORK BROADCASTING phases of the development of radio broadcasting could be jus-tified only by a study of the public need, as indicated by publicdemand, for this type of service. If this demand was to belimited in extent, or to give evidence of a public interest whichwould have no permanency, the expenditure of effort or capitalon radio broadcasting would be obviously unjustified. In order to continue its research in radio telephone transmis-sion, begun in 1915, the Bell System established, late in 1921, an experimental station known as 2XB. This was located at463 West Street, New York City, at what is now the Bell Tele-phone Laboratories. About the middle of 1922, StationWBAY was put into operation at 24 Walker Street, New YorkCity, and shortly thereafter Station 2XB was given the callletters WEAF. Stations WBAY and WEAF were operate
