As graphic program developers reverse engineered the various formats, they could save the data in a different format. It was only later on that someone wanted to convert one of those special formats to something else. For them and their intended users, everything worked just fine. Generally, they were to work within a specific program or specific hardware. Over the course of history in graphic file evolution, there have been many manufacturers that have created their own format, but not with the intent that images in their format would ever need converting to anything else. Almost no one "needs" 50 formats unless they are in the business of converting a wide range of formats to a more common format. The point is not that anyone needs 50+ formats.
