The people buying your ads want to know how many people saw them. If your ad is embedded in 3D space, when did someone “see” it? If they were standing at a 10 degree angle for 6 seconds does that count? 11 degrees and 5 seconds?

With video ads they want completion rates. With all ads they like people to be able to click through and engage further with the product. None of these questions have satisfying answers with embedded ads. That’s why they never took off.
