Market share actually does in some respect account for a sum of existing products in use, how that is calculated will depend on the reporting entity. Usage share turns out to be super easy to capture these days, we do it by looking at the browser string of a request to a web server. Most big sites are putting out this type of data so a relatively clear picture emerges. For a company like microsoft or apple market share is a more useful measure because it helps them plan/predict their supply chain so that they have the right amount of inventory in the right place at the right time. But from a developer perspective usage share is more interesting for obvious reasons. In this case the numbers are still basically the same. |
