To this day, Microsoft Office remains the dominant office software suite, a position it has held since the 1990s. While competitors have emerged to appeal to different customer niches (Google Docs with collaboration or iWork for Mac users), for many people the value of using Office lies in the fact that many others use it; it has stood the test of time. This illustrates one of the strategic benefits of platforms: Once established, they are hard to dislodge. Exit from a platform usually requires customers to leave in a coordinated fashion.
