FM radio was invented in the 1930s to improve some of the faults of AM radio. AM would get static from electrical sources, it had limited quality and would sometimes get interference from other stations. Edwin Armstrong devised a new approach to transmitting the radio signals, and FM radio was born.
Armstrong met with opposition from all sides. His invention would mean costly retrofits for existing stations all over the country. Most of the stations were owned by the record companies, Read the rest of this entry »
Since I live out in the “sticks,” as my family loves to call it, I don’t have access to DSL or cable Internet. While I had managed without the web for quite some time, my wife was finally able to convince me that we needed to get “connected.” A few weeks ago, I found a great deal on satellite Internet (see satelliteinternetspecials.net/high-speed-technology.html) and, before I knew it, I had a big satellite dish sitting on my roof.
To my pleasant surprise, I was also able to get Sirius XM satellite radio service in addition to my Internet service. I absolutely love it. For around 15 bucks a month, I have access to more than 130 channels spanning everything from music, news, sports, traffic and weather. Surprisingly, there is no static whatsoever with the satellite reception – even out in the country where I live. And best of all, there are no commercials on the music stations.
My favorite thing about Sirius satellite radio, though, is its portability. The satellite tuner I got is extremely compact and designed to be transported easily between my house and my car. This is extremely convenient for me since I’m always on the move.
My wife can have all the Internet she wants. I’ll take satellite radio.

Multiple disruptive forces mad materialized in the public arena during the economic turmoil. The Communist Party, isolationists, anti-Semites and other divisive groups had worked to Read the rest of this entry »

Radio has always been a great opportunity for companies to advertise their products to consumers. While television and the internet has swooped in lately to take some of the advertising pie away from radio broadcasters, it continues to be a very lucrative medium to this day. Radio advertising was never more prominent, however, than it was in the 1940s.
Radios came into being commercially in the early 1920s, very soon after mechanically operated record players hit it big with consumers. The difference was that since Read the rest of this entry »
