In the Ad Scheduler (Until you have the ability to actually Manage Ads then this feature needs to be Renamed) there should be an option to choose which type of Ads your channel shows, ie Lower Thirds, pic-in-pic, display or audio.

For example most Broadcasters may actually be open to showing 22min/hour of ads (current max setting in scheduler) if those 3mins of ads every 8min on stream were lower thirds ads that didn't block access to viewing the stream or listening to its audio.

Then in the Scheduler which you could now call a Manager, show what the potential commission would be on showing each ad-type (Obviously full screen & audio ads would payout more vs lower thirds etc)

Give Broadcasters CHOICE and we will use your tools/features especially if it potentially means higher revenues for the broadcaster & a better viewing experience for the viewer.

On a side note; have the ability to choose which ad types get shown would be a key metric that your Internal Ad Sales Group could use to see what Inventory they can fill and what ad rates they can get from those sales. For example if everyone wants to show 10min+ of lower third ads per hour then the sales group could then go out and fill those advertiser/marketing orders faster. It's like the whole Wishlist factor, a wishlist interest proves the potential of a future sale.
