Yes, the U.S. federal government and a lot of the states, and the U.K. were probably earliest off the mark with the open government initiatives. But there are lots of countries and jurisdictions that have done well. There are now over 400 jurisdictions, national and subnational governments, that are involved and have signed off on the principles of open government. Data is the easiest for a lot of people to start with, so a lot of them have already moved down this path.
In Canada there are lots of good examples. The B.C. government is doing quite well. The City of Edmonton is doing quite well. There are lots of success stories to point to.
