Blog #7 EOTO Presentations

One presentation I was very interested by was the Telephone/Cell phone. In 1874, Alexander Graham Bell discovered the principles of the telephone, He experimented with Thomas Watson to create the first telephone connection. The first outdoor wire was strung in 1877, it was a commercial telephone service that began in the US. The payphone was invented by William Gray in 1889. It allowed people to make phone calls in public places when they didn't have access to their own phone. In 1891, the rotary phone was invented by Almon Strowger. 

This was a very important invention because it allowed people to be able to call others independently in your own home. Oliver Lodge demonstrated wireless communication over 150 yards, which marked the beginning of cell phone technology like we know now.Motorola demonstrates telephones where people can call wirelessly which birthed cellphones in 1972. In 1989, Motorola introduced the first "Pocket" cell phone, called MicroTAC. During the mid to late 1990s, cell phone companies made their mobile phones lighter, faster, cheaper and, slimmer, to evolve the mobile phone. In 1999, Motion introduced the Blackberry 850 which began the Blackberry craze. Then in 2007, Apple launched their first iPhone which changed the game completely.
