Technological advancements over the last century have meant many of us now own multiple computers - desktops and laptops, mobile phones, tablets.
The modern personal computer as we know it is only a recent invention.
Scroll down to see how this technology has evolved over the past 70 years.
In 2013, tablets will outsell laptops. Workforces are becoming increasingly more mobile and the presence of desktop computers in the office is declining.

3½ inch floppy disk
Following the initial launch of various new disk formats in the early 1970's, 1982 saw the launch of the then-standard 3½ inch floppy disk, first manufactured by Sony.
Birth of the modern internet
In 1982, the internet protocol TCP/IP was standardised, allowing the introduction of the concept of a worldwide network of interconnected TCP/IP networks, referred to as The Internet.
The development of Tetris
Tetris was released on 6 June 1984 and was the first entertainment software to be exported from the USSR to the US. Whilst initially launched for 1980’s home computer platforms, it was the Game Boy version launched in 1989 that helped the game achieve its huge success.

The Commodore PET
The Commodore Personal Electronic Translator was a personal computer produced in 1977. The first model, the PET 2001 came with either 4 kb or 8 kb of 8-bit RAM. Due to huge demand of the computer, and backed up orders, the 4 kb version was quickly dropped.
UNIX growing in popularity
The first commercial installation of UNI took place in 1972 in New York. During the late 1970’s the influence of Unix in academic circles led to a large scale adoption of Unix by commercial startups, including Darwin which forms the core of Apple’s OS X and iOS.
First portable calculator introduced
The first portable calculators were introduced in Japan in 1970. These included the Sanyo Mini Calculator, the Canon Pocketronic and the Sharp Micro Compet.
Computing in the 1960s

Hewlett Packard enter the industry
Hewlett Packard entered the desktop computer business in 1968 with the introduction of the 9100A. The desktop was referred to as a calculator to stop it being rejected by the market as it didn’t look like an IBM, who were at the time dominating the market. The 9100A weighted 18 kg and cost around $5000.
BASIC programming language designed
BASIC (Beginner’s All-purpose Symbolic Instruction Code) is a group of generic, high-level programming languages designed for ease of use. Designed by John Kemeny and Thomas Kurtz in 1964, the language was developed to help more students learn to code.
ARPANET developed by the US military
In 1969 the Advanced Research Projects Agency Network (ASPANET) was introduced as one of the world’s first operational packet switching networks, the first to implement TCP/IP making it the progenitor of the modern internet.
Computing in the 1950s
The UNIVAC I was the first American computer designed from the outset for business and administrative use. Owners Remington Rand joined up with CBS to correctly predict the 1952 presidential election results, contrary to the pollsters’ favorite.

The British mathematician and computer pioneer Alan Turing published a paper describing the potential development of human and computer intelligence and communication.
Worldwide computers reach 100
It is estimated that in 1953 there was 100 computers in the world. Magazine Popular Mechanics quoted ‘Computers in the future may weigh no more than 1.5 tons’, the equivalent of 1,360 kg.
Computing pre 1950s
First electronic computers
Very few electronic computers were available before 1950. Previous famous non-electronic computers, such as Turing's Enigma machine were more common during the earlier World War years.
COLOSSUS was the world's first electronic computer, and was developed for British codebreakers during World War II. The Mark I prototype was operational in February 1944, but was superseded by Mark II later that year. The National Museum of Computing have since rebuilt a Mark II COLOSSUS at Bletchley Park.
