While history recognizes Guglielmo Marconi as the father of wireless communication, it was Canadian Reginald Aubrey Fessenden who showed the world that it was possible to send the human voice via wireless. On Dec. 24, 1906, he transmitted the first audio signals. He played an Ediphone recording of Handel's Largo, played Oh Holy Night on the violin and read from the Bible. This event proved that wireless communication could be used for more than simple Morse code.

History has recorded many pioneering advances in technology, and a great number of them have molded radio broadcasting into the technology that it is today and is becoming tomorrow.

To celebrate radio's 100 years of audio transmission, Radio magazine is preparing a special tribute to the technology of radio broadcasting, and we want your help.

We will recognize the top 100 technology innovations that have influenced radio's evolution or are used in radio today. You can help us identify this technology.

Send your ideas to radio@penton.com. While the name of the product or technology is the basic information, include as much information about your submission as you can. Submit complete products or general technologies. We'll create a list of all the ideas and have a panel of Radio magazine readers and contributors determine the final list.

We'll announce the results in the December issue — just in time to celebrate the 100^th anniversary of Fessenden's accomplishment.

E-mail your ideas to radio@penton.com by Aug. 1, 2006. Everyone who submits an idea will be entered into a drawing to win a Radio magazine t-shirt. Submit as many ideas as you like. It will also help us if you tell us why you think your idea should be recognized.
