First U.S. advertisement for a radio receiverIn 1905, the first U.S. advertisement for a radio receiver appeared in this day's issue of the Scientific American. The one-inch advertisement was for the Telimco, which offered for $8.50 a "Complete Outfit comprising 1-inch Spark Coil, Strap Key, Sender, Sensitive Relay, Coherer, with Automatic Decoherer and Sounder, 4 ex. Strong Dry Cells, all necessary wiring, including send and catch wires, with full instructions and diagrams." This system was suitable for sending dots and dashes (not full audio). The advertisement also said, "Guaranteed to work up to one mile. Send for Illust. pamphlet." It was offered by Hugo Gernsback of The Electro Importing Company. The product name was an acronym of the company name. |
