Google TV Ads shutdown in around 2012. I know a lot of tech companies have worked their way into streaming video ads, but as far as traditional tv ad buying this it a bit of a black box.

Comcast Spotlight and Spectrum Reach both put out their own self-service platforms but it's limited to zipcode purchases and isn't the greatest. I'm looking for something similar where you can put in parameters, budget, upload creative, and bid and buy time slots that appear on national TV programs all from within a web interface.

It seems there is a huge opportunity here if not.
