>Cyberdog was an OpenDoc-based Internet suite of applications, developed by Apple Computer for the Mac OS line of operating systems. It was introduced as a beta in February 1996 and abandoned in March 1997. The last version, Cyberdog 2.0, was released on April 28, 1997. It worked with later versions of System 7 as well as the Mac OS 8 and Mac OS 9 operating systems.
>Cyberdog derived its name from a cartoon in The New Yorker captioned "On the Internet, nobody knows you're a dog."

As was Sun's original "HotJava" browser, implemented in Java of course, which was less formally component based than OpenDoc (since Java didn't have a comparable user interface component system like OpenDoc at the time, but it was at least very object oriented, modular, and extensible). HotJava served the purpose of opening a lot of people's eyes to the possibilities of Java and the web, but, like CyberDog, it was ahead of its time, and wasn't fully developed into a viable product, and served more as a technology demonstration and source of inspiration.

>HotJava (later called HotJava Browser to distinguish it from HotJava Views) was a modular, extensible web browser from Sun Microsystems implemented in Java. It was the first browser to support Java applets, and was Sun's demonstration platform for the then-new technology. It has since been discontinued and is no longer supported. Furthermore, the Sun Download Center was taken down on July 31, 2011, and the download link on the official site points to a placeholder page saying so.
Unfortunately, neither CyberDog nor HotJava (nor Netscape, until JavaScript finally arrived on the scene) had scripting languages built in, which I believe is an essential ingredient to the success of web browsers and component systems (and text editors like Emacs, and user interface editors like HyperCard or HyperLook or Bongo, or content management systems and blogging tools like Frontier and Radio Userland, etc). Even something as terrible as Microsoft OLE, which evolved from Visual Basic VBXs, was successful because it was built around a scripting language (Visual Basic for VBX, but OLE opened it up to any language via COM/IDispatch/ActiveX/IScriptingEngine/etc).
