Telephizzle / Radio

Coming out of WWII, the predecessor of the telephone, the telegraph, had become the most quick and reliable means of communication, especially over long distances. With the newly developed radio in frequent usage, the telephone had combined with this technology to bring a new, cheaper version of the phone. Using this invention, leaders could quickly and easily communicate with other governmental officials or military commanders, giving them vital information at the touch of a button (or the twist of a dial).

By 1950, radio transmissions could reach only up to about 40MHz (Megahertz; versus the range of about 90 - 110 MHz used in today's radios), meaning that transmissions were very short and weak. However, with such a small range of frequencies, many transmissions could interfere with one another, causing these new radios to be considered a failure. Finally, in 1964, car phones were able to effectively communicate with another desired phone without the interference of the last 20 years. However, the devices are rather large, and can't be carried around without a backpack. However, over time, these grew smaller and smaller into the devices we carry today.
