Broadcasting through three sta
tions on regular schedule Is only
one Of the phases of the American
Telephone and Telegraph Company's
investigation of the possibilities of
radio broadcasting. It's programs for

points as distant as Chicago, st. Louis
and Kansas City and transmitted

New York city.
A special effort is being made to de-
termine the preference Of the radio
audience with rgard to programs.
/ Every suggestion, criticism and express
sion of approval is carefully tabulated
in statistics, which are used as
guide in arranging the broadcasting
programs. The skill with which pro-
grams involving the use of many
musical instruments, such as the Cap

WEAF an enthusiastic radio follow

Consequently. when Col. f. II. r.
| Green decided TO give New England
| the highest grade of radio programs.
J he sought a. means OF securing
WEAF's programs for his own sta

! mated to send these by special long
distance circuits to South Dartmouth
in order TO operate the 500-watt West

colonel has erected on his estate.

grams for broadcasting from stations

nected by wire telephone lines with
studios in New York. Already the
studios at WEAF are supplying

immensely amplified by a series of
