A web widget is a portable chunk of code that can be installed and executed within any separate HTML-based web page by an end user without requiring additional compilation. They are derived from the idea of code reuse. Other terms used to describe web widgets include: gadget, badge, module, webjit, capsule, snippet, mini and flake. Web widgets usually but not always use DHTML, JavaScript, or Adobe Flash.
Widgets often take the form of on-screen tools (clocks, event countdowns, auction-tickers, stock market tickers, flight arrival information, daily weather etc).

The use of web widgets has been increasingly proposed as a marketing channel that could replace the less effective targeted banner ads and take advantage of the viral distribution in social networks. This usage has been criticized as ineffective [1] on the basis that users of a social space are not mainly in a mindset receptive to information exposition but one of content creation. source:wiki
