Netscape, which soon overtook Mosaic as the market-leading web browser, also featured a throbber. In version 1.0 of Netscape, this took the form of a big blue "N" (Netscape's logo at the time). The animation depicted the "N" expanding and contracting - hence the name "throbber". When Netscape unveiled its new logo (a different "N" on top of a hill), they held a competition to find an animation for it. The winning design (featuring the new-look "N" in a meteor shower) became very well known and almost became an unofficial symbol of the World Wide Web. Later, Internet Explorer's blue "e" enjoyed similar status, though it only functioned as a throbber in early versions of the browser.
