BroadFall by SpringServe enables publishers to create a broadcast tier as a part of their waterfall. This tier makes asynchronous calls to the associated demand tags, and proceeds with the rest of the waterfall if none of broadcasted tags serve an ad.
To enable a supply tag for BroadFall, navigate to the Demand Tags tab on the supply tag level and select "Enabled" on the BroadFall switch.
Once this is selected, a broadcast icon will appear next to the demand tags in that waterfall. Selecting this icon will put the selected demand tag into the broadcast tier.
With BroadFall, publishers can also run header bidding demand tags using SpringServe's JS VPAID as a part of their waterfall within this broadcast tier. To learn more about implementing header bidding tags, see: Implementing Header Bidding tags via BroadFall.
