50% is not a monopoly last I checked. It’s an oligopoly but at least a highly competitive one with two very different value propositions (privacy/closed ecosystem vs openness/lower prices). Basically every computing landscape ends in oligopoly due to network effects - personal computers 1990s (Windows vs Mac), video game consoles (Nintendo vs Sony vs Microsoft), mainframes 1970s (IBM vs 7 dwarves), etc. Argument is almost as strong at 50% IMHO. At 90% not so much (Google Search, Microsoft Windows, Android almost globally)
- newbie578 6y agoIn some industries a monopoly can even be with a marketshare about 25%, but nevermind, 50% is widely regarded as the average threshold, as you can see on justice.gov :( "Some courts have stated that it is possible for a defendant to possess monopoly power with a market share of less than fifty percent.(29) These courts provide for the possibility of establishing monopoly power through non-market-share evidence, such as direct evidence of an ability profitably to raise price or exclude competitors. The Department is not aware, however, of any court that has found that a defendant possessed monopoly power when its market share was less than fifty percent.(30) Thus, as a practical matter, a market share of greater than fifty percent has been necessary for courts to find the existence of monopoly power.(31)" https://www.justice.gov/atr/competition-and-monopoly-single-firm-conduct-under-section-2-sherman-act-chapter-2 https://www.justice.gov/atr/competition-and-monopoly-single-...
