concurrent viewers
CCV (concurrent viewers) is the number of people watching a stream at the same moment, read live rather than as a lifetime total, so it reflects the honest size of the room an ad is in while it renders.
Concurrent viewers: the number of people watching a stream at the same moment. Because it is read live rather than as a lifetime total, CCV is the honest size of the room an ad is actually in while it renders.
CCV rises and falls across a stream, so it is usually shown as an average and a peak over a window of time. It counts who is present, not who followed once and left.
