Danforth Weed Sees Television First a Luxury Market ( Continued from Page 1) fired, there is every reason to believe that the demand for sets will bring down the present estimated costs of receivers mentioned by radio engineers. “In England sets are already selling far below the prices predicted for similar American products. Insofar as sound receivers are concerned — a market that is competitive — we undersell England by a very wide margin. There’s every reason to believe that we’ll beat Britain on video receiver values, too. Television will be an immediate attraction to those sponsors who will pay the price to pioneer in sigh-and-sound merchandising even before sets reach the mass production stage. But there won’t be a very wide gap between the commercial start of television and volume video receiver sales. Early bookers of television time at initial rates may benefit by a considerable ’bonus circulation’.” Calendar Offer on KIDO Electrical Equipment Sales Ass’n decided to find out where their money was going as sponsor of KIDO’s (Boise) evening “Listener’s Digest.” They made a simple offer of a 1938 calendar to all “Digest” listeners. Commentator Dooley Riddle announced the offer five times. Response was immediate. Calendars were scarce in five states and one Canadian province.
