A widget is an external application that can be added to a device as an app or to a web page as a piece of software.
Widgets are applications that could have different functions, but are usually solely intended to serve one purpose.
In web pages, web widgets are varied and can be anything from a weather information ‘window’ to a widget tracking the stock exchange.
The first web widget was created by Trivia Blitz in 1997 and was a game applet offered by uproar.com.
