An explanation: each coloured shape in the graph represents a platform. The horizontal axis is time. The vertical axis represents the number of games released. So the height of a shape on a given point in time indicates the number of games released for that platform that year. The total height of the graph on a given point in time shows the total releases that year.
[All data taken from MobyGames. Of course, the graph is only as complete as our database is - meaning we currently undercount some new digital game platforms like PC/Mac, digital console, and iOS/Android since we don't 'scrape' those databases automatically - and the dropoff in 2015 and 2016 is because we're still entering newer games into the database.
