The first public Opera. Version 2.00 was announced in April 1996 as shareware for Windows: you could try it, then buy a license.

It was small, fast and ran well on the modest PCs of the time, which became Opera's calling card for the next ten years.

The research browser that started it all. Opera 1.00 was written by Jon Stephenson von Tetzchner and Geir Ivarsøy at Telenor, before they founded Opera Software later in 1995. It was never sold, but it was shown publicly at the WWW '95 conference in April 1995, and it already had the idea that defined early Opera: several pages open at once, as windows inside one application.
