Mosaic's functionality

Describe the changes that occurred with the browser's introduction.

The Internet's graphical user interface (browser) had a revolutionary effect on how the Internet's information was displayed and viewed. With the introduction of Mosaic[1] in 1993, users could view a combination of text, graphics, sound, and even movies onscreen, in a magazine type format. Not only could data types be combined to provide an informational message, but its data parts could reside anywhere on the Internet. The Internet offered something that had never been done before, the ability to view the same document, in the same way, on different operating systems (Apple, Microsoft Windows, or Sun Solaris). The most modern browser that support HTML 5 is Google Chrome.

The browser's effect on industry

Early Internet adopters faced bandwidth problems when attempting to download graphically rich Web pages over plain old telephone service. It wasn't long before the telecommunications industry recognized the need for increased bandwidth, more phone lines, and better service.
Document management now needed to concern itself with how to display documents in HTML. For example, Adobe PDF[2], and the Acrobat viewer were early providers of document solutions. Issues such as whether to convert documents to HTML or offer them as a downloadable resource became predominant. Data processing was heavily affected as the light browser client began asking servers to do heavier processing, as well as multiple servings of single documents.

The browser's effect on business

Companies and individuals started to think about the audience that now was viewing Web sites. Not only were academics and techies accessing the Internet, but the average public was now interested. Businesses began recognizing the Internet as another medium for advertising, and professional quality Internet publishing became a reality.
Browsers such as Mosaic, Netscape, and Internet Explorer opened Internet access to the public and business.
A new publishing and information channel was created, in addition to the existing structures and technologies, and e-Business followed.
