Definition S curve
Explain: Imagine a graph showing, for each month since smartphones originally became available, how many people in the US bought their first one. The line would rise slowly at first, when only the early adopters got them, then quickly as these phones became more popular, and then level off again once nearly everyone had one. This graph's line would form a stretched-out “S” shape. The “S curve” applies to many other phenomena and is often mentioned when someone predicts that a rising value will eventually level off..
