The transition from 17x17 to 19x19 was much earlier than that (except in Tibet, which still used 17x17 until recently). Go was played on 19x19 in China at least as early as 200 AD, although it seems 17x17 go was still played there a few centuries later. It looks go was always on 19x19 in Japan, since it was introduced there about the year 735.
19x19 is a good size since the center is about the same size as the edge and corners, so strategy is more balanced.

"17x17 is boring" because the border have "just the right size" to be stable, that is standard well known corner josekis and extensions allow to take the border without problem, whereas on the 19x19 there is additional space, which give weakness, so possibility for invasion/erosion/trouble. I hope some strong go player on the list can better explain this. my 2 cents.
