The animation depicted the "N" expanding and contracting - hence the name "throbber". In version 1.0 of Netscape, this took the form of a big blue "N" (Netscape's logo at the time). Netscape, which soon overtook Mosaic as the market-leading web browser, also featured a throbber. The Netscape logo, as seen in the top right of the browser window Clicking on the throbber would stop the page loading later web browsers added a separate Stop button for this purpose. As the user could still interact with the program, the pointer remained normal (and not a busy symbol, such as an hourglass) therefore, the throbber provided a visual indication that the program was performing an action. One of the early (if not the earliest) uses of a throbber occurred in the NCSA Mosaic web browser of the early 1990s, which featured an NCSA logo that animated while Mosaic downloaded a web page. Clicking the throbber itself might perform another action, such as opening the program's website, or pausing or canceling the background action. It is normally possible for the user to continue interacting with the program while the throbber animated one such possibility may be to press a "stop" button to cancel the action. Once the action is complete, the throbber returns to its resting frame. Throbbers are typically a still image (known as its resting frame), unless the program is performing an action, during which time the throbber is animated in a loop to convey to the user that the program is busy (and has not frozen). Throbbers take various forms, but are commonly incorporated into the logo of the program. Usually the throbber is found at the side of a program's toolbar or menu bar. In contrast to a progress bar, a throbber does not indicate how much of the action has been completed.
