Which browser's logo is a blue 'e'?

The browser whose logo is a blue “e” is Internet Explorer. Microsoft introduced the familiar blue e emblem with Internet Explorer 3, released in 1996; it later became one of the most recognizable symbols in early web browsing.

The logo’s italic letter e was often shown with a ring or orbit around it, suggesting the internet and motion. Because Internet Explorer was bundled with Windows for many years, the icon became a routine part of millions of computer desktops. At its peak around 2003, Internet Explorer held about 95% of browser usage share.

A common mix-up is Microsoft Edge. Edge was Microsoft’s successor to Internet Explorer and uses a different wave-like blue-green symbol, rather than the classic blue e with an orbit. Internet Explorer 11 was the final major release, while Edge also retained an Internet Explorer mode for older business websites and legacy technologies such as ActiveX.

Microsoft retired Internet Explorer’s regular desktop support on most Windows 10 systems on June 15, 2022.
