Cello was the first web browser designed for Microsoft Windows. Cello was released in 1993, and the client program was written in the programming language C++ by Thomas Bruce. Thomas Bruce founded the Legal Information Institute at the Cornell Law School. Cello was designed to work on Windows 3.1: Windows 3.1 used Winsock -- the Windows network software -- to access network services. Winsock was used by Cello to access TCP/IP networks; the Internet is a collection of TCP/IP networks that voluntarily agree to interconnect using TCP/IP. Cello supported images -- many early Unix based browsers only supported text and could not render images. However, Cello was largely criticised for the quality by which it did render webpages (HTML documents). The browsers Netscape Navigator and Internet Explorer were launched in the mid-1990's: this caused Cello to fall into disuse, and its final version was released on the 16th of April, 1994.


In 1992, the Legal Information Institute launched the first website dedicated to the 'law'. However, Thomas Bruce, while promoting the Legal Information Institute's website, found that the majority of lawyers were using computers running Windows and not Unix. Therefore, Thomas Bruce realised that many lawyers did not have access to the World Wide Web, because, the vast majority of browsers were only compatible with Unix. The World Wide Web was launched in 1991, and during that era the vast majority of computers that connected to the Internet ran a version of Unix. Therefore, developers focused their efforts on developing web browsers for the Unix platform. To increase web access for lawyers Thomas Bruce began to develop a Windows browser, and he realised that goal on the 8th of June, 1993.


The image, provided below, is the Cello logo, and was published in 1994.

The Cello logo, which was provided for the first browser ever developed for the windows operating system in 1993.

Users of Cello, were referred to as: Cellists. The minimum requirements for Cello was stated to be: an IBM cpu 386SX chipset and at least 2MB of memory. The final version of Cello was capable of retrieving documents from the following Internet services: World Wide Web, Gopher, FTP, CSO/ph/qi, and Usenet News.
