The First Browser - WorldWideWeb (Nexus)

   Tim Berners-Lee invented the WOrld Wide Web or WWW as we know it today in 1989, deploying a working system by 1990. Berners-Lee was the first to invent the browser, and it was simply called WorldWideWeb since it was the only way to see the Web. Tim later rechristened this browser 'Nexus', to distinguish between the program and the abstract information space "www" which was typed in the Uniform Resource Locator (URL). WorldWideWeb was written in Objectice-C and it would let users browse "http:", "news:", "ftp:" and local "file:" spaces.

   Tim wrote the program for this browser on a Next computer. THe browser was the best at the time, since it was the only one. If you look at the browser closely, you will see that buttons and features in the browser look similar in Internet Explore. Here's a brief low-down on the functionality of the browser.

   The menu bar looked like a primitive version of the Windows Desktop, and clicking on it would provide a list of options similar to the Windows of today. THe Navigate menu had things such as "Back", "Next" and "Previous", and the last two were useful when you followed a link from a list of links-they meant "go back a step and then take the next link from the same page."

  The "Link" menu had options such as "Mark all" which would remember the URL of the current page where you were. "Mark selection" would make a link target for the selected text, give it an ID, and remember the URL of that fragment. "Link to Marked" would make a link from the current selection to whatever URL you had last marked. So making a link involved browsing to some where interesting, hitting [Command] + [M], going to the document ou were writing and seleting some text, and then hitting [Command] + [L]. "Link to new" would create a new window and prompt for a URL, and then make a link from the selection to the new document. You never saw the URL-you could of course always find documents by following the link to them.

   Using the "Style" menu, you could load a style sheet to define how you wanted your documents (Web pages) rendered. You could also set the paragraph style to an HTML element's style such as heading1, heading 2, list element, etc., and then this implied an HTML structure in which the document was written back.

   At that time, the "X" close box was unique to Next, and according to Tim, Windows copied it. The broken X in the "Tim's home page" window means that the document was in the process of being edited and was unsaved. Now that we have talked about the first Web browser, lets move on to find more about other browsers.
