First released January 23, 1993. I remember those early days. We were excited by the possibilities.

Mosaic changed everything. Because Mosaic was fast and enabled people to see images within pages, it quickly gained fans. Earlier browsers could only show images in separate windows. Moasic was also the first “easy to use” browser. It also popularized icons, bookmarks, and a more attractive interface.
