Radio Broadcasting.
Development of new apparatus for use in broadcasting continued,
and the Presidential inauguration ceremonies were broadcast for the
first time. While successful experiments were conducted in the field
of international broadcasting for entertainment, this phase of broadcasting
 is not yet in regular operation. With this accomplishment
in view, proposals are being carefully considered for increasing the
power of sending stations, and a high-power experimental station
has already been erected at Boundbrook, N. J., with a maximum
power one hundred times greater than that heretofore used by the
stations in New York and Washington.
Any estimate of the sales of radio-receiving apparatus is almost
impossible. © The receipts from such sales by the Radio Corporation
for 1922 were $11,286,489; for 1923, $22,465,091; for 1924, $50.-747,202;
 for 1925, $46,251,785.
Telephones.
Fifty years ago the first complete sentence was transmitted by
telephone. During 1925 more than 813,000 telephones were added
bo the Bell system, bringing the total number interconnected in this
system to 16,720,000, of which over 4,000,000 are owned by independent
 connecting companies. The United States operates over 61
per cent of the world’s telephones, Europe being second with 28 per
sent. More than 50,000.000 toll and eXchange connections were
handled daily.
The American Telephone & Telegraph Co. and associated companies
 reported an increase in wire mileage of almost 14 per cent
during 1925, as compared with 15.6 per cent in 1924. Of this increase,
 5,522,436 miles were in cable conductors, both aerial and
anderground, and 57,485 in open wire, as compared with 5,148,000
and 222,000, respectively, in 1924. At the end of 1925 approximately
 90 per cent of the total wire of 45,474,000 miles were in aerial
and underground cable and 10 per cent in open wire.
During the year 527,000 telephones operating through automatic
exchanges "were added by the Bell system, bringing the total to
1,496,000 or 1214 per cent of the entire number, as compared with
8.7 per cent at the end of 1924. The toll cable from New York to
