Who Invented the Computer Mouse?

Who Invented the Computer Mouse?...

The mouse was invented by Douglas Engelbart in 1965 while working at the Stanford Research Institute. He was also helped by his colleague Bill English. The history of the computer mouse shows he never profited from it. The patent had expired long before the device came into wide usage. Early Prototypes Before Engelbart developed the mouse, the trackball had already been invented. In 1954, the Canadian Navy created the device for utilization on the DATAR system. The mouse Engelbart made was large and had two wheels. Although he invented the mouse in 1965, he only patented it in 1970. He called the device an XY Position Indicator for a Display System. The basic idea was actually inspired by the telautograph which was designed back in the 19th century. A couple of years later (1972) Bill English created the ball mouse. This was an improvement from the original and marked a significant point in the history of the computer mouse. Unlike the mouse with wheels, the ball allowed the mouse to move in any direction. The device was included in the Xerox computer where English was working at the time. Other Mouse Types In 1975, another type of ball mouse was created by Jack Hawley also while working at Xerox. Honeywell later produced a wheeled mouse which moved along its axes. However it was in the École polytechnique fédérale de Lausanne that the standard mouse appeared. The project was headed by André Guignard and Professor Jean-Daniel Nicoud. Their design would change the history of the computer mouse. They changed the rubber ball so that it became harder and more stable. They also increased the buttons to three. This would remain the standard until the mid 1990s when the third button...
Who Invented Napster?

Who Invented Napster?

Napster easily made a name in the world of online service by offering good quality music files, which people were able to share instantly with each other. It directly went against the interest of the music industry, which claimed that this particular type of service was in fact involved in massive violations of copyright. However, the idea behind it was so good that it eventually led to the development of peer-to-peer file-distribution programs that are decentralized. Besides these and many other interesting details, it is also good to know who invented Napster. The Invention of Napster Who invented Napster? Based on reports, a computer programmer named Shawn Fanning was the one who invented the idea behind such innovative online music file-sharing service during that time. He then formed a partnership with an entrepreneur named Sean Parker. Together, they released the original version of Napster some time in June 1999. Unlike other services such as USENET, Hotline and IRC, the service centered on MP3 music files. Furthermore, many people loved it right away because of its efficient but user-friendly interface. Additional Facts and Other Important Information Upon its initial release, people found so many different reasons to love the service provided by the original Napster. First, it owned a system comprised of a wide range of downloadable music. Secondly, the service offered people the wonderful opportunity to download and enjoy songs that were once very difficult to obtain such as concert bootleg recordings, unreleased music albums and singles as well as older songs. Furthermore, it also gave people the chance to get digital copies of songs that made use of other formats like cassette tape and LP. Because Napster facilitated the transfer of copyrighted music, the Recording Industry Association of...
Who Invented the word Blog?

Who Invented the word Blog?...

Who invented the word “blog”? Introduction Blog is short for weblog. The term weblog was first coined in December 1997 by an American blogger named Jorn Barger. He used it to describe he would “log the web” as he surfed online. Later another blogger named Peter Merholz changed weblog to “we blog” in a 1999 post. Soon people were dropping the other word and just used “blog.” Jorn Barger Biography Jorn Barger was born in Yellow Springs, Ohio in the year 1953. He was the editor of “Robot Wisdom,” a widely read blog from the early days of blogging. Barger liked to blog about the Irish writer James Joyce and artificial intelligence. He participated heavily in Usenet newsgroups in the 1990s, writing about Joyce, Kate Bush and other topics. He came up with a newsgroups “law” stating that the more interesting one’s own life is, the less he or she posts in online discussions. Barger created the Robot Wisdom weblog posting links about politics, technology, internet culture, books, artificial intelligence and other subjects. It became an online journal recording his day to day intellectual and reading activities. Barger’s blog gained wide acclaim. The influential New York Times remarked that the Robot Wisdom made life easier for people. With the blog, one could gain quick access to quality information without having to search the web by oneself. The Register praised Barger as well, saying no one could read news better than he. However the blog pioneer is not without critics. He has come under fire several times for allegedly racist comments against the Jews and Judaism. Blog Basics Blogs have gone from being simple web journals to big business. There are several types of blogs, such as: Personal blogs –...
Who Invented the MP3 Format?

Who Invented the MP3 Format?...

The mp3 format was invented by the MPEG Group in 1991. The history of the mp3 format indicates several people worked on the project but the accredited inventors were Ernst Eberlein, Thomas Sporer, Karhl Heinz Brandenburg, Bern Grill and Bernd Kurten. Development Mp3 was the offshoot of OCF and PXFM. Those who worked on the project were mainly focused on how people were able to hear music. Through the course of their work, the Fraunhofer Society (which became part of the MPEG group) started looking for ways for music to be compressed and yet maintain its high quality. After working on it for several yeas, the standards were implemented in 1991. Further refinements would follow and it was integrated with MPEG 2 which came out in 1994. Release to the Public A study of the history of the mp3 format will reveal the Fraunhofer Society produced the encoder on July 7, 1994. A few months after its release, an mp3 player called Winplay 3 was released as well. Unlike other music formats, Mp3 offered a lot of advantages. The first was its small size. Using the 128 bit compression, a 5 minute song only came in at about 5 MB. This was a huge improvement over the WAV formats whose size was ten times that. In addition, the quality was very high, almost CD like. This became possible due to limitations in hearing. Mp3 removed the bits in the sound file that people wouldn’t be able to hear. By taking out these extraneous pieces, the size was reduced without sacrificing the sound quality. Popularity and Widespread Use Through the 1990s, the history of the mp3 format shows the tremendous impact it made on the Net. The release of Winamp...
Who Invented Video Games?

Who Invented Video Games?...

No single individual can be credited with creating the first video game. But as this brief history of video games will show, several people played a prominent role in its growth and expansion. The Earliest Video Games The records show that in 1952, A.S. Douglas developed a graphical computer game. The game was Tic Tac Toe and it was created on the EDSAC vacuum tube computer. However it isn’t generally considered to be a video game. The first real video game is said to be William Higinbotham’s Tennis for Two. This game came out in 1958. The next innovation came in 1962 when Steve Russell came out with Spacewar! The game was played on a MIT PDP-1 mainframe computer. The history of video games would change in 1967 when Ralph Baer created a game called Chase. It was the first game to be played on a TV screen. The 1970s Arcade Games Several important developments took place in the 1970s. Nolan Bushnell and his associate Ted Dabney came out with Computer Space, and the video arcade was born. In 1972 the game Pong came out (Pong is often erroneously referred to as the first video game). Later that year Bushnell and Dabney would team up again and form Atari Computers. It was also in 1972 a home video game console became available. It was produced by Magnavox. Called the Odyssey, it came with a dozen games. Four years later, the Fairchild Video Entrainment System appeared. A study of the history of video games will show that a lot of the classic games came out during the 1970s. Following the success of Atari, Space Invaders came out in 1978, and was also well received. In 1979, colors began to be...
Who Invented Email?

Who Invented Email?

The history of email began with Ray Tomlinson in 1971. The program was created while he was working for the US government, specifically ARPANET (the future Internet). Tomlinson’s Work Tomlinson was working for the United States Defense Department in 1968. He was a computer engineer at the time. He started by developing an application called SNDMSG. Its purpose was to let ARPANET users relay messages. Originally, SNDMSG was local. That is, the messages could be sent only to users of that same computer. Tomlinson used the CYPNET (a transfer protocol) on the SNDMSG application. This allowed SNDMSG to send and receive email to any computer within the ARPANET network. This was how the history of email began. The First Email Message Tomlinson utilized the @ symbol for a simple reason: it would enable him to know which individual was at the system. Back them, the @ was inserted between the computer host and the user name. The first email Tomlinson sent was QWERTYUIOP. Early Use of Email Following Tomlinson’s invention, the service started to be used in the ARPANET. It was connected to the FTP (File Transfer Protocol). The FTP would eventually be replaced by the SMTP (Simple Mail Transfer Protocol). FTP is still sometimes used today when downloading files off the World Wide Web. However it is important to note that email is much older than the Internet. Email was being used at ARPANET in the 1970s, long before the Net came into being. Other Email Prototypes The history of email shows that MIT had already demonstrated its potential back in 1961 with Compatible Time Sharing System (CTSS). This technology permitted users to gather and share files online. The other prototypes permitted communication on the mainframe. However it...
