What are some old proprietary file formats that have become unreadable due to the vendor going bust, withdrawing support, losing documentation, or otherwise disappearing?

There are plenty of abandonware products out there which save data that no other software could read, simply because that data has no meaning outside the context of that application - e.g. games. So ignoring those, I'm thinking about data that could feasibly have some utility in another application.
Like, maybe an old spreadsheet program that nobody has written a converter for. But I can't think of any instance where reverse engineering has not come along and saved the day.
