There are other notable existing and defunct browsers such as Worldwideweb, the very first web browser written by Tim Berners- Lee in 1990, and the first popular browser called Viola (released in 1991). There is also Konqueror (released in 2000 and bundled with many Linux distributions), without which Safari would have to have been based on a seamonkey sites and Flock sites. Sadly, though, even at their height these browsers never managed to amass even 10 per cent of web users between them.
