come a permanent feature OF AmerI-
can radio programs.
The Spring of 1925 witnessed the
first concerted venture into the realm
of the short waves and an accom-
panying victory for the radio eX-
plorer. The Westinghouse Electric
and Manufacturing Co. had brought
the short waves to the attention of
the public in 1924, when entertain
ment programs were shuDted on
lengths below 100 meters from Pitts.
burgh to Australia and New Zealand
The 1928 visitation of these low
wave lengths. however. deived into
the very highest frequenCies. and, with
the leaders Of the American Radio
Relay League and the officials of the
Naval Radio Research Laboratories
showing the way, resulted in the sue
Cessful transmission and reception OF
around the world.
Embodened by their success, the
same leaders will continue their work
in 1925, hoping to establish the wave
lengths of from l to 10 meters as
the future medium of the majority
of wireless transmission.
In the early Summer came the
worlds first demonstration of -"radio
vision" the term applied by DIR. {.

Power Gradually Raised,
i o1so ,,-,s in tho Summer that
one of the most violent popular radio
prejudices-that against the use of
superpower for broadca sting-was
smashed. Quietly, but sure of their
ground, the leading stations aban-
doned the 50O-watt limit for broad
casting and. with the sanction of
the Department of Commerce, trans
nitters were stepped up gradually 10
maximum of kilowatts. Instead
condemnation came praise from
the listening public, and the 5-kilowatt
init was raised to 90 kilowatts in
n epochal broadcast demonstration
by the General Electric Co.
Instead of causing interference, as
mad been predicted by superpOwer OPP
ponents, there was distinct sharpness
of tuning and a notable increase of
broadca sting range. This 50-kiloWatt
station was given permission to op-
crate at stated periods, and there toll
lowed in November a second super
power station, owned and operated by
the Radio Corporation of America,
lust outside New York City.
Chain Broadcasting Grows.
In the meantime, chain broadcast
ing, which was introduced by the
American Telephone and Telegraph Co.
in 1924, was growing by leaps and
II, To- ono of IN
extensive hook-ups ever arranged for
a single event was accorded the IN
augural address of President Coolidge.
During the Summer the chain of sta
lions broadcasting regularly through
the week increased from 3 to 10, and
in some cases even more. The world
series add the leading Eastern foot
ball games of the Fall we're all booked
through the chain by leading stations
throughout the country.
With all of these forces It work. and
with the ever-increasing desire of or
CARNATIONS, businesses, schools. pro-
moterS and institutions to get on the
air with their own broadCaSting sta
tions, it became evident during the
Summer that radio had come to the
crossroads. Obviously, if the United
States was to avoid a hedlam in tho
, ether, it was necessary to call halt
on the laisseZ-faire policies extended To
broadcastinS and wireless communica
ton. and to place some rules and regu-
lations on it's progress.
And SO, in November, the radio in
terestS of the United States assembled
| in Washington. under the auspices of
the Department of Commerce and seri-
ously confronted the future, with a full
knowledge of where they wanted to
go, but not quite sure of the way in
which they should get there.
Ask United States Supervision.
In this frame of mind, it took but
three days, under the direction of
Secretary Of Commerce Hoover to
ask unanimously that supervision of
