Google Web History (previously Google Search History) is a feature of Google Search and provided by Google, in which all search queries and results that a user clicks on are recorded to. The feature is only available for users logged in to a Google Account. The feature was renamed from Search History to Web History on April 19, 2007. A user's Web History is used to personalize search results with the help of Google Personalized Search.

The World Wide Web ("WWW" or simply the "Web") is a global information medium which users can read and write via computers connected to the Internet. The term is often mistakenly used as a synonym for the Internet itself, but the Web is a service that operates over the Internet, just as e-mail also does. The history of the Internet dates back significantly further than that of the World Wide Web.

The hypertext portion of the Web in particular has an intricate intellectual history; notable influences and precursors include Vannevar Bush's Memex,IBM's Generalized Markup Language, and Ted Nelson's Project Xanadu.

The concept of a home-based global information system goes at least as far back as "A Logic Named Joe", a 1946 short story by Murray Leinster, in which computer terminals, called "logics," were in every home. Although the computer system in the story is centralized, the story captures some of the feeling of the ubiquitous information explosion driven by the Web.

"In August, 1984 I wrote a proposal to the SW Group Leader, Les Robertson, for the establishment of a pilot project to install and evaluate TCP/IP protocols on some key non-Unix machines at CERN ... By 1990 CERN had become the largest Internet site in Europe and this fact... positively in Europe and elsewhere... A key result of all these happenings was that by 1989 CERN's Internet facility was ready to become the medium within which Tim Berners-Lee would create the World Wide Web with a truly visionary idea..."

Google Web Toolkit (GWT /ˈɡwɪt/) is an open source set of tools that allows web developers to create and maintain complex JavaScript front-end applications in Java. Other than a few native libraries, everything is Java source that can be built on any supported platform with the included GWT Ant build files. It is licensed under the Apache License version 2.0.

GWT emphasizes reusable, efficient solutions to recurring Ajax challenges, namely asynchronous remote procedure calls, history management, bookmarking, internationalization and cross-browser portability.

GWT version 1.0 RC 1 (build 1.0.20) was released on May 16, 2006. Google announced GWT at the JavaOne conference, 2006.

Release history:

In August 2010, Google acquired Instantiations, a company known for its focus on Eclipse Java developer tools, including GWT Designer, which is now bundled with Google Plugin for Eclipse.

With introduction of the Dart (programming language), Google has reassured the GWT community that GWT will continue to be supported for the foreseeable future, but also hinted at a possible rapprochement between the two Google solutions for "structured web programming". They've also admitted however that a number of engineers previously working on GWT are now working on Dart.
