Back in the early days of radio - and then later television - companies used big-name media personalities to promote their wares. To a lesser extent some of that happens today as well. Advertisements like this one for RCA's Radiotron vacuum tubes appearing in a 1934 issue of Radio News magazine is typical of what you would have seen in the era. In it, none other than Bing Crosby was joined by a trendily dressed woman who was rejoicing in her decision to buy a new radio that contained those newfangled "Micro-Sensitive" receiver tubes. Radio was considered a mystical entity by most people, and in 1934 there were still many households that did not yet host a radio of any sort. Rural residences often did not have AC service and relied on storage batteries to power machinery and appliances. Farmer Brown had to haul a wagon loaded with heavy lead-acid batteries to town to get them recharged. Some of the more prosperous ruralites had windmill- or water-driven generators to produce the necessary power. In fact, in 1934 a complete power generator setup could be purchased from the Sears, Roebuck catalog. RCA Cunningham Radiotron Ad
