Widgets
Embeddable chunks of code have existed since the start of the World Wide Web. Web developers have long sought and used third party code chunks in their pages. It could be said that the original web widgets were the link counters and advertising banners that grew up alongside the early web. Later, ad and affiliate networks used code widgets for distribution purposes.
A widget is anything that can be embedded within a page of HTML, i.e. a web page. A widget adds some content to that page that is not static. Generally widgets are third party originated, though they can be home made. Widgets are also known as modules, snippets, and plug-ins.
Rich media, interactive entertainment widgets were first syndicated in large volume in 2001 by miniclip. Widgets are now commonplace and are used by bloggers, social network users, auction sites and owners of personal web sites. They exist on home page sites such as iGoogle, Netvibes, Pageflakes, SpringWidgets and yourminis. Widgets are used as a distribution method by ad networks such as Google’s AdSense, by media sites such as Flickr, by video sites such as YouTube and by hundreds of other organizations.
Applications can be integrated within a third party website by the placement of a small snippet of code. This is becoming a distribution or marketing channel for many companies. The code brings in ‘live’ content – advertisements, links, images – from a third party site without the web site owner having to update.
Widget destinations
End users can utilize Web Widgets to enhance a number of web-based hosts, or drop targets. Categories of drop targets include social networks, blogs, wikis and personal homepages. Although end users primarily use Web Widgets to enhance their personal web experiences, or the web experiences of visitors to their personal sites, corporations can potentially use Web Widgets to improve their web sites using syndicated content and functionality from third party providers.
Security considerations
As any program code, widgets can be used for malicious purposes. One example is the Facebook “Secret Crush” widget, discovered in early 2008 by Fortinet as luring users to instal Zango malware.
Widget management systems
Widget management systems offer a method of managing widgets that works on any web page, such as a blog or social networking home page. Many blog systems like Wordpress or Movable Type come with built in widget management systems as plug-ins. Users can obtain widgets and other widget management tools from widget gallery sites such as Widgetbox or SpringWidgets.
