Apologies if this is already under discussion (first-time poster) but I'm interested in adding cost per second (or cost per hour) to the next version of openRTB as a custom pricing model in the bid request.
But in theory it could include any kind of pricing model, including cost per time.
The way it would work: a bid request would be sent that includes a pricing_model field specifying one (or more) types of accepted bid response types: CPM, CPC, CPS, etc. Bidders willing to buy via one of the pricing models would send back responses. If no pricing_model is specified in the bid request, CPM would be assumed.
Thoughts? As more publishers and networks such as FT, Economist, Parsec, and others are selling on time, this will become increasingly useful.
