But why serve house ads repeatedly when you can tap into programmatic exchange and monetize at least a portion of those impressions? Programmatic doesn't need to be first look on all impressions.
If I'm on drdobbs.com in one tab and only being served house ads, but in my second tab I have retargeted ads being served to me, that's lost revenue for drdobbs.com
The reason you see Interop over and over again is that this is a house ad - placed by UBM on a UBM site - in lieu of having any paid advertising.
We run house ads and banners too - free to us - for our conferences on sdtimes.com
