What advertisements that are available varies by where a player is. The ads were no longer there on July 1 for players in the USA.
The end of June was the end of the 2nd quarter of 2014.
Advertisers wanting to reach US players paid to advertise using the extra view videos only up to the end of June.
So it is not a 'problem'. WGT's ad selling department just needs to sell more advertising time.
