Today, many tablet PCs, portable electronic devices, and a variety of technologies exist to help people communicate and share opinions or thoughts. And the past? People drew, scratched, painted, engraved and finally wrote down their stories or thoughts. The typewriter was the first writing machine in history. Among the many typewriters, the IBM Selectric I typewriter was the most revolutionary. The Selectric typewriter was not only a stepping stone for subsequent generations of typewriters, but it was also an important part of the historical event of feminism, and the speed and convenience of the model helped the workforce in history. There could be no computers, iPads, or many other electronic objects without the history of typewriters, especially the revolutionary technology of the IBM Selectric typewriter. The inception of the typewriter is unknown, but the first "official" invention dates back to 1714, the patent for which was granted to Enrico Mulino. The first typed letter was by William Burt who typed a letter to his wife in 1830. The typewriter was born from the search for a method to allow blind people to read and write using raised letters. It is a mechanical interface that shares a fundamental connection between the act of tactile impression and the ideal of evocative expression. It was also the role of "digital" transmission in the literal sense, which operated with the fingers. The most common typewriter keyboard layout is "QWERTY" and the word "typewriter" could be typed on the top row of the machine and was useful for those who could not write. There are different types of typewriters such as portable, electronic and standard invented models. IBM, one of the top typewriter companies in the United States, introduced the revolutionary and most remarkable electronic edition... half of the paper... computer inventions. By 1975, Selectric accounted for approximately 75 percent of the U.S. electric typewriter market. The first Selectric model to hit the typewriter market offered revolutionary features to office workers around the world. This revolutionary machine saved time and reduced errors. The influence of the typewriter was significant. In particular, typewriters introduced women into the world of work, contributing to liberation. Great literary works have been composed by typewriters, and they have also played important roles in film, art, and popular culture, elevating them to iconic status. Throughout the 1960s and 1970s, the Selectric was the iconic secretary's car. The famous relationship between Selectric typewriters and secretaries is still celebrated in films and TV series depicting the era, including the current hit TV series Mad Men.
