Started listening in 1949. Still listening. Have a bunch of good radios both old and new. I’m sorta upset that we may be losing AM. it’s foundational in many ways. I’ve always had fun listening.😃

The invention of the radio is traditionally attributed to Guglielmo Marconi, but, two years before, the Brazilian priest and inventor Roberto Landell had already worked with electromagnetic waves. He managed to transmit the voice of some people over a distance of approximately 8 km, but was overlooked for lack of investment.

Sorry, did this in my freshman year of high school. I really am NOT an expert on radio. Video productions, maybe, but please don't look to me as a lone source on any aspects of radio. If you have questions on video productions or anything of that nature then by all means, ask away.

Your statement about AM not penetrating structures well is incorrect. Propagation and penetration is a function of frequency, not modulation. In fact, due to the lower frequency of most AM stations (MF) it actually penetrates and propagates much better than do most FM transmissions, which due to the nature of the additional bandwidth required for FM, are typically on higher frequencies (VHF/UHF).

@@aparichituduunknown4354 Your question would need a large book or hour long video to answer. However I will offer my two cents. RCA Victor contributed quite greatly around 1920. They developed a really good AM radio with about five vacuum tubes. It was called superheterodyne based on an intermediate frequency of 455 kHz. Pretty deep right? Radio became wildly popular and practically every family had one within a few years.

Transistors replaced vacuum tubes, not the "crystals" of crystal radio sets. Crystal radios used no power supply, driving headphones (not speakers) from the energy actually contained in the broadcast signal. Oh, and FM has a shorter range than AM.

1: Tesla DEMONSTRATED radio transmission and reception wiith a radio controlled boat before Marconi. Yes, the very first application of radio was remote control. 2: Whaakes FM radio less static-plagued than AM radio is due to the signal structure, NOT the frequency. The AM band actually is a much bett short and long range communication band, whereas the commercial FM band is only good for line-of-sight communication (regardless of whether you use an AM, FM, LSB or USB signal format). 30 years Army radio communications

You missed the most important part in 1878 where David Edward Hughes created a new type of carbon microphone which a phenomenon mistaken for induction but was actually the first radio waves ever produced.

Wow. To think radio is free transmission and power is not, although they basically used the same technology involving the emr and the towers is something to understand only when you watch this video and time travel to the late 1800s

Ehrm. Tesla had the patent. The patent agency changed it to Marconis favour. Marconi had applied for an almost identical transmitter. Short after Teslas death he got the patent back post mortum.

Sorry, but AM has by FAR the longest range, be it long or short wave, it follows the curvcature of the earth, FM does not and has very limited range. Let's wise up here folks.
