I don't know if $150,000,000 is a good number or not, but it probably is a lot of money for sure. This is actually not a surprise because frankly, these kinds of ads shouldn't have existed in the first place.<p>As are so many things on the internet, this was a short lived opportunity that made some people a lot of money, but is not a long term viable business model.<p>However, like many of these short lived businesses, there will be a few who made enough money to pivot into other adjacent opportunities. The short sighted ones who build their businesses like Google's policies would never change will be left holding the bag.<p>The same thing happened in CPA based affiliate marketing for things like ringtones, work from home offers, and acai berry supplements after the FTC cracked down.
