The end of June was the end of the 2nd quarter of 2014.
Most of the video Earn Free Credits ads running in June stopped running at the end of the month.
Some of those advertisers have re-upped with WGT for at least part of the 3rd quarter.
Expect the same thing to happen at the end of September.
Advertisers won't spend advertising dollars in countries where they do not sell their product. So players in a country like Vietnam won't see the same advertisements players in the USA see, and players in the USA won't see ads targeted at players in Vietnam.
