So the question is obvious: Would you as either advertiser or publisher want to show/create ads at a size of 970x250, the so called billboard? Let us know what you think and perhaps also why! We might implement it at Lukads.
So you'd only do this against an abnormal high price. I get your point as it's a quite remarkable format and it sure will cost more than the other sizes but I think that 100$ / 1000 visitors is kind of pushing it
