Since browsers are not sold (ok, let's agree that ~99% of browsers are not sold), there's not a sales market to talk about. Ask any mobile phone industry analyst, or a product manager (or product marketing manager) at a mobile phone OEM, or a sales manager at a telco, for the definition of mobile phone market share and they will tell you "the share of sales during a period of time." >> The same goes with Apple and Android, when you talk about market share This is 100% not true. Ask anyone in the industry and they will agree that it represents sales, not installed base. As a point of reference, I used to work at Google, in Android specifically. Previous to that, I spent 10 years in the mobile industry, much of it briefing industry analysts & journalists.
