Computer: How Steve Jobs Changed the World

- Personal computers with graphical user interfaces: For a long time, computers were only controlled via the command line, with characters being entered on a dark screen. After it was founded in 1976, Apple was the first company to bring out the Apple II with colored graphics. The Apple Lisa computer, launched in 1983, introduced the operation of programs with a menu and in a window. In 1984 the Apple Macintosh became the first commercially successful computer with a graphical user interface.

- Renewal of the cartoon: Jobs bought "Star Wars" inventor George Lucas in the early 1980s for ten million dollars from a department for computer graphics. This resulted in the Pixar animation studio. After years of hard work with no economic success and a further investment of ten million dollars, it opened a new market in 1995 with the first long computer-animated cartoon "Toy Story". In 2006 Jobs sold Pixar to Disney. This made him the entertainment company's largest shareholder and billionaire.

- iPod players and music downloads: Jobs was ridiculed by many when he introduced the iPod music player in 2001. The device - although more expensive than competing offers - quickly became the market leader. With the iTunes online shop launched in 2003, Apple became the world's largest music seller. A range of films, software and apps followed. The recipe for success was the close connection between iTunes and mobile devices as well as support for Windows PCs.

- The smartphone revolution with the iPhone: Jobs introduced the iPhone in 2007 with the phrase "We have reinvented the telephone". It sounded grossly exaggerated - but the smartphone with a touch-sensitive display actually set standards for the entire industry in terms of operation and appearance. In addition, the iPhone turned the industry upside down, because for the first time the focus was no longer on the device, but on the software installed on it - the apps.

- The iPad and the advance of tablet computers: For several unsuccessful attempts, tablet computers were considered a dead end - until Apple and Jobs came up with the iPad. The device, which was launched in spring 2010, turned tablets into mass business in one fell swoop. As with the smartphone, numerous other manufacturers are trying to build on the success and are developing their own tablet computers, but the iPad continues to dominate the market. Jobs saw the iPad as an ambassador for a "post-PC world" in which classic computers are becoming less important. (dpa)
