 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.The aging Communicator code proved difficult to work with and the decision was made in late October to drop the code branch of the Communicator 4.5 core rendering engine and start from scratch using the standards-compliant Gecko rendering engine.Gecko featured in the Mozilla web browser, which, with a few additions, Netscape 6 was based on.
