The advent of the Internet, and the realisation of the potential of 'open source' licensing like the d20 system in particular, has given rise to an explosion of games publishers, particularly small ones run more as a hobby than as a means of earning a living. This can only be a good thing, as games hitherto known only to their inventor and his friends can be made available worldwide - sometimes by download (paid or free), and as popularity grows it's possible for 'real' publishing as well.
