APR 4, 1964 IBM's System/360 Released The System/360 was the first computer on the market to base its data processing off of microminiaturized computer circuits. It changed how computers were made. Before, they were specially made and often customized based on the customer's needs. However, this computer used a basic structure to suit the needs of a large userbase. This allowed greater compatibility- no longer did customers have to edit the programming of a file to use it on another computer. JAN 1, 1971 First email sent The first network email was sent by computer engineer Ray Tomlinson in 1971. The email to himself said “something like QWERTYUIOP”. JAN 1, 1983 First Form of Internet Released JUL 3, 1969 General Public Introduced to Online Networking Vinton Cerf and Robert Kahn collaborate to create the TCP, considered to have codified the basics of the internet. The U.S. Advanced Research Projects Agency Network (ARPANET) was the first public packet-switched computer network. It was first used in 1969 and finally decommissioned in 1989. ARPANET's main use was for academic and research purposes. In 1969, the UCLA (University of California, Los Angeles) put out a press release regarding possible wireless transmissions of data through networks. The triggered a series of events that would lead to the creation of email and the internet by Professor Leonard Kleinrock. MAR 1, 1973 Xerox Alto Created The MS-DOS 1.0 was Microsoft's first computer. It could hold up to 32 megabytes of data, and was actually quite primitive. However, it allowed programmers to have peer-to-peer interactions through the creation of PC user groups, and opened up the door for new talent to make a mark. JAN 1, 1984 First Macintosh Released Considered one of the most innovative computers of all time, the Alto featured a mouse, menus, and many features that are now standard. However, its contributor, Xerox, did not see itself as a computer company, and thus did not market it until 1981 as the Star 8010. Unfortunately for Xerox Steve Jobs took a lot of inspiration from the Alto and beat the 8010 to the market. Jobs's company, Apple is now a technological leader, and the handling of the Alto is considered one of Xerox's biggest errors. The first computer in Apple's Macintosh line, simply called the Macintosh. It was the first commercially successful computer to use a mouse and a graphical user interface (GUI). It cannot accept new chips or be opened with ease, perhaps forshadowing similar issues with changing iPhone batteries. JAN 1, 1987 T1100 Released AUG 1, 1981 MS-DOS 1.0 Released The (Toshiba)T1100, manufactured by Toshiba, was the first laptop to be released to the market. Bulky by today's standards, but at the time the mere concept of a portable computer was viewed as revolutionary. 1989 Worl Wide Web Day
