Apple Products Evolution

The Macintosh initially sold well, but follow-up sales were not strong due to its high price and limited range of software titles. The machine's fortunes changed with the introduction of the LaserWriter, the first PostScript laser printer to be offered at a reasonable price, and PageMaker, an early desktop publishing package. The Mac was particularly powerful in this market due to its advanced graphics capabilities, which had necessarily been built in to create the intuitive Macintosh GUI. It has been suggested that the combination of these three products was responsible for the creation of the desktop publishing market.
In 1985 a power struggle developed between Jobs and CEO John Sculley, who had been hired two years earlier. The Apple board of directors instructed Sculley to "contain" Jobs and limit his ability to launch expensive forays into untested products. Rather than submit to Sculley's direction, Jobs attempted to oust him from his leadership role at Apple. Sculley found out that Jobs had been attempting to organize a putsch and called a board meeting at which Apple's board of directors sided with Sculley and removed Jobs from his managerial duties. Jobs resigned from Apple and founded NeXT Inc. the same year.
• 1986–1993: Rise and fall
Having learned several painful lessons after introducing the bulky Macintosh Portable in 1989, Apple introduced the PowerBook in 1991. The Macintosh Portable was designed to be just as powerful as a desktop Macintosh, but weighed 7.5 kilograms (17 lb) with a 12-hour battery life. The same year, Apple introduced System 7, a major upgrade to the operating system, which added color to the interface and introduced new networking capabilities. It remained the architectural basis for Mac OS until 2001.
