Apple had the money to buy "Logic" from a German company called "Emagic", and scrap their Windows version. Logic then soon became industry standard.

Voilà.

Logic isn't the industry standard though. PT has long been thought of as the industry standard, although that's changed recently with Cubase/Ableton Live/FL/Logic becoming massively popular as well. Really depends on genre/application (EDM, acoustic, film/game/media, etc).
