According to my good friend Grayson Gold, TrafficVance is finally serving international pops as of now! That includes all the major english speaking countries: United Kingdom, Australia, Canada, and New Zealand. They have been serving text links in these countries for a while now, but for those of us that are addicted to pops this is a massive announcement. Lead Impact had the edge internationally for a long time, but I guess all those GameVance installs you guys have been promoting have paid off.
Keep up the good work, and get those international campaigns up!
