Only because iAd (https://en.wikipedia.org/wiki/IAd) was a horrific failure.

In early 2011, the minimum buy price on the platform was $500K. By midyear, $300K. By early 2012, $100K. Early 2013? $50 (no K missing, just fifty bucks).

I believe you that it was a failure, but that doesn't follow from the minimum price dropping. Perhaps as they gained confidence in the system, they allowed smaller buys with smaller prices (but still just as profitable).
