The Macintosh, however, was expensive, which hindered its ability to be competitive in a market already dominated by the Commodore 64 for consumers, as well as the IBM Personal Computer and its accompanying clone market for businesses. Macintosh systems still found success in education and desktop publishing and kept Apple as the second-largest PC manufacturer for the next decade. In the 1990s, improvements in the rival Wintel platform, notably with the introduction of Windows 3.0, then Windows 95, gradually took market share from the more expensive Macintosh systems. The performance advantage of 68000-based Macintosh systems was eroded by Intel's Pentium, and in 1994 Apple was relegated to third place as Compaq became the top PC manufacturer. Even after a transition to the superior PowerPC-based Power Macintosh (later renamed the PowerMac, in line with the PowerBook series) line in 1994, the falling prices of commodity PC components and the release of Windows 95 saw the Macintosh user base decline.
Which platform, when improved in the 1980's, took market share from Macintosh?
A: unanswerable

Encompassing a wide variety of post-Romantic styles composed through the year 2000, 20th century classical music includes late romantic, modern, high-modern, and postmodern styles of composition. Modernism (1890–1930) marked an era when many composers rejected certain values of the common practice period, such as traditional tonality, melody, instrumentation, and structure. The high-modern era saw the emergence of neo-classical and serial music. A few authorities have claimed high-modernism as the beginning of postmodern music from about 1930. Others have more or less equated postmodern music with the "contemporary music" composed from the late 20th century through to the early 21st century.

contemporary music
