Cello was an early graphical web browser for Windows 3.1, developed by Thomas R. Bruce of the Legal Information Institute at Cornell Law School, and released as shareware in 1993. While other browsers ran on various Unix machines, Cello was the first web browser for Microsoft Windows, using the winsock system to access the Internet.〔(【引用サイトリンク】title=The Legal Information Institute - A Quick Overview )〕 In addition to the basic Windows, Cello worked on Windows NT 3.5〔(【引用サイトリンク】title=NT and NTAS INTERNET SLIP/PPP CONNECTIVITY FAQ )〕 and with small modifications on OS/2.〔 Cello was created because of a demand for Web access by lawyers, who were more likely to use Microsoft Windows than the Unix operating systems supporting earlier Web browsers, including the first release of Mosaic. The lack of a Windows browser meant many legal experts were unable to access legal information made available in hypertext on the World Wide Web.〔〔(【引用サイトリンク】title=Web Browser History )〕 Cello was popular during 1993/1994, but fell out of favor following the release of Mosaic for Windows and Netscape, after which Cello development was abandoned.〔(【引用サイトリンク】title=A Future of Browsers )〕〔You can view yahoo browser statistics at http://web.archive.org/web/20021204042351/http://www.cen.uiuc.edu/~ejk/bryl/ which show Cello being used.〕 Cello was first publicly released on 8 June 1993.〔 A version 2.0 was announced, but development was abandoned. Version 1.01a, 16 April 1994, was the last public release.〔(【引用サイトリンク】title=Communicating with the LII )〕 Since then, the Legal Information Institute at Cornell Law School has licensed the Cello 2.0 source code, which has been used to develop commercial software.〔 The browser is no longer available from its original homepage.〔The original cello site at http://www.law.cornell.edu/cello/cellotop.html is no longer up. The original ftp site at ftp://ftp.law.cornell.edu/pub/LII/Cello is no longer up. The original gopher server at gopher.law.cornell.edu:70/11/listservs/cellol/ is no longer up.〕 However, it can still be downloaded from mirror sites.〔Cello can still be downloaded at http://browsers.evolt.org/?cello/ .〕 ==Development and history== The development of Cello started in 1992, with beta versions planned for June 1993 and a release for July 1993.〔(【引用サイトリンク】title=May World-Wide Web News )〕〔(【引用サイトリンク】title=WEB HISTORY DAY: PIONEERING SOFTWARE AND SITES )〕 It was publicly announced on 12 April 1993. The Legal Information Institute at Cornell Law School created the first law site on the Internet in 1992 and the first legal website in 1993. However, at the time, there were no web browsers for the Microsoft Windows operating system, which was used by most lawyers. Thus, to allow lawyers to use their website, the Legal Information Institute developed the first Windows-based Web browser. This was made possible by a grant from the National Center for Automated Information Research.〔This can be seen in the "About Cello" dialog in Cello. It is also stated in the "Notices, Acknowledgments, Disclaimers" section of the included .hlp file in Cello.〕 Although other browsers at the time were based on CERN's WWW libraries called libwww, PCs of the time were not powerful enough to run the UNIX-oriented code.〔 As a result, Thomas Bruce had to rewrite most of the WWW libraries to work on Microsoft Windows.〔 It should also be noted that unlike most commercial browsers at that time, Cello didn't utilize any of Mosaic's source code and thus had a different look and feel. Steven Sinofsky, president of the Windows division at Microsoft wrote in a June 1994 email: ''We do not currently plan on any other client software (the upcoming release of Windows 95 ), especially something like Mosaic or Cello.'' Nonetheless, on 11 January 1995, Microsoft announced that it had licensed the Mosaic technology from Spyglass, which it would use to create Internet Explorer.〔 On 15 August 1995, Microsoft debuted its own web browser Internet Explorer 1 for Windows 95. While it did not ship with the original release of Windows 95, it shipped with Microsoft Plus! for Windows 95. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cello (web browser)」の詳細全文を読む スポンサード リンク
