  Crystal Sets

  The earliest radios were crystal set radios typically built by hobbyists at home. They were limited in range and volume, and required headphones to listen to the broadcasts, which made using the crystal sets an individual activity (MacLennan, Windover, and Borck 2024a).
   

  Technological advancements

  
   

  In 1925, the contribution from Canadian Edward S. Rogers led to the development of alternating current (AC) tubes which enabled radios to control amplification while also connecting to home electricity, eliminating bulky batteries within radios. In addition, the creation of the electro-magnetic cone-speaker in 1927 replaced the horn speaker by amplifying the sound of radio without distortion (MacLennan, Windover, and Borck 2024b). These advancements enabled increased sound quality and convenience in radios, which moved radios from semi-private spaces in the home (such as the attic, basement and garage) into public spaces such as the living room and kitchen (Windover and MacLennan 2017, 71).

  
  Radios into the home

  As a result of these significant technological advancements combined with the rise of Canadian broadcasting in the 1920s, there was a growing popularity in new self-contained floor sets. These radios were promoted beyond their technical specifications and were renowned for the craftsmanship of their wooden cabinets tailored to the taste of the upper class. Although popular in the homes of the affluent, the floor sets were out of reach for most Canadians as they were expensive—typically worth the weekly wage of an average Canadian male worker (MacLennan, Windover, and Borck 2024c). Furthermore, there was sparse radio signal over large areas and a lack of electrification in homes. Therefore, many Canadians still continued to use their crystal sets (Windover and MacLennan 2017, 14).
