It seems to me that if the development of the internet has done nothing else, it's opened up the wide world of gun dogs to interested gun dog enthusiasts. Back in the 1980s and early 90s for instance, when Brittanys were first starting to appear, I would hear distant rumours of this great unknown breed called 'Wirehaired Ponting Griffons' but there was no way to find any real information about them, not to mention finding a breeder. Now there are unbounded resources for such things, such as this post from Project Upland contrasting and comparing 38 breeds, all by clicking on the link (there is no way this will copy-paste in an understandable way).
