In 1998, an informal group called the Mozilla Organization was formed and largely funded by Netscape (the vast majority of programmers working on the code were paid by Netscape) to coordinate the development of Netscape 5 (codenamed "Gromit"), which would be based on the Communicator source code. However, the aging Communicator code proved difficult to work with and the decision was taken to scrap Netscape 5 and re-write the source code. The re-written source code was in the form of the Mozilla web browser, on which, with a few additions, Netscape 6 was based.
