One of the greatest innovations in communication technology to date is the telephone. With it, we've connected over mountains, across oceans, and to opposite ends of the world. We can convey important information quickly and efficiently, and now, with cell phones and smartphones, we can send important data, capture memories, and explore the Internet, all from our mobile phone. The history of the telephone is an amazing timeline of experimentation and discovery.
1672: Robert Hooke created the first acoustic telephone in 1672. Very much like the two-soup-can toys you made as a child, Hooke found that sound could be sent over a wire or string from a mouthpiece on one side to an earpiece on the other.
1838: Samuel B. Morse discovered that you could transmit messages by pressing down or releasing a button in intervals to transmit a pattern of sounds. This was known as Morse code.
1858: Cyrus Field sought to lay the first transatlantic telephone cable, connecting England and the U.S. by telegraph. This project was met with setbacks before it was completed in August 1858.
1867: Dots and dashes were flashed with signal lamps for the first time at sea in 1867. The idea came from British admiral Phillip Colomb, who used the signal lamp design of Arthur C.W. Aldis and devised a code to communicate with other ships. The code was much like Morse code; eventually, Morse code won out.
1876: Since coming to America as a teacher of the deaf, Alexander Graham Bell had sought a way to transmit speech electronically. He invented the telephone in March 1876.
1880: Bell set up a lab and worked to improve his invention. The result? The photophone, which was capable of sending sound on a beam of light. Bell made what was essentially history's first wireless call!
1915: Bell makes the first coast-to-coast phone call in January 1915. This was the first long-distance call from a land line. Bell's call helped make long-distance calling a reality.
1927: The first telephone service from the U.S. to the U.K. was set up in January 1927. The first phones were radio phones, but there were fading and interference issues. Three minutes of time on these phones cost nearly $10.
1930: AT&T created a two-way videotelephone called the Iconophone. The Iconophone let people see, hear, and reply to each other in real time. The idea didn't see much commercial success.
1946: In June 1946, a telephone call was made from an automobile-based phone for the first time. It wasn't a very large mobile network, due in part to the high cost of installation.
1947: In 1946, an electronic gizmo known as a transistor was created by John Bardeen, Walter Brattain, and William Shockley. This would replace large vacuum tube systems and allow computers to be merged with electronics, the beginnings of smartphone development.
1973: Martin Cooper places the first cellular mobile call to Joel Engle, a rival at Bell Labs. The first cell phone took a year to recharge, and the maximum talk time was only 30 minutes.
1977: The FCC officially launches the first primary cellular test network. It only opened in few select areas, like Chicago, Washington, D.C., and Baltimore.
1979: Ship-to-shore communication takes a leap forward as the International Maritime Satellite Organization (INMARSAT) is established. Its aim was to provide reliable communication to marine vessels for increased safety.
1981: The first automated commercial cellular network, called 1G Generation, is launched in Japan. At the same time, the Nordic Mobile Telephone system is established in Denmark, Finland, Norway, and Sweden.
1989: Only a few years after "The Brick" is released, Motorola develops the lightest cellular device on the market. The phone is called the MicroTAC and weighs in at only 12 ounces.
1995: Sprint opens the first personal communications service. It was the first cellular network designed for private use for individuals who own cellular phones.
1998: A company called Iridium puts a canopy of 64 satellites is into place. They also made the first hand-held satellite phones, replacing "bag" phones with ones that were much less cumbersome. This move would lead to development of the modern smartphone.
2003: Technology is developed to transmit phone calls over Internet protocols. Long-distance charges could be avoided through the use of established computer networks.
2008: Both the iTunes Store and the Android market open up for smartphone users in 2008. This heralds the beginning of a huge surge in the popularity of apps.
2010: Smartphones continue to develop in 2010. The first 4G handset is released this year, bringing data onto consumers' phones at blazing-fast speeds.
