Google Calendar is proof Netscape was right
 

If people needs further proof of AOL and Time Warner's lack of understanding of the Net and the software/IT world besides the firing of all the programmers on Netscape's payroll that were contributing for years to the Mozilla project, one dark day in 2003 - people who was an invaluable asset for the corporation, allowing it to control its own software destiny and create more opportunities to itself, I refer people to Netscape Calendar. Yes, very few people remember it, but it worked, and it was active. Archive.org keeps a copy I think, dating back to April 1999.

depends, the right timing of a product is important too
