We have to skip all the way to 1965, when the U.S. launched Intelsat 1 into orbit. And that made wireless communication possible and less expensive than laying down more trans-Atlantic cable. While Intelsat was mainly used for transmitting telephone and T.V. signals between Europe and North America, the satellites launched thereafter (including the latter Intelsat models) would have wider range, and be instrumental in our third event: transmitting the signals for the first mobile phone call made by researchers on April 3, 1973. Isn't it kind of weird that those mobile phones are now used mostly for texting?
