For the past 20 quarters, sales of Apple Macs have grown faster than the PC market Apple Macintosh, was the first successful personal computer to feature a mouse and a graphical user interface (GUI), and it was introduced on the 24th of January 1984. About a year later, Microsoft introduced Microsoft Windows in November 1985 in response to the growing interest in the GUIs.
When the Macintosh was launched in 1984, computers running the MS-DOS operating system were nearing a dominant position in the market.The IBM PC,were quickly cloned and four years later “PCs” were selling at the rate of 2 million/yr. The Mac only managed 372k units in its first year.
PC was outselling the Mac by a factor of nearly 6. It
turned out to be a high point. The ratio by which the PC outsold the
Mac only increased from there.
When Windows 95 launched in 1995 it negated most of the advantages of
the ease of use of the Macintosh and the PC market took off. The ratio
reached 56 in 2004 when 182.5 million PCs were sold vs. 3.25 million
Macs.(source : Asymco)
