Silliest headline ever. As I recall in 1984 the world had Tandy, Leading Edge, Epson, Dell, AT&T, NEC, Atari, Commodore and countless others were all competing with IBM and Apple.
Also, in 1984 one of the major competitors to the Macintosh was the Apple II. The Mac didn't overtake the Apple II series in unit sales until about 1987.
