The mis-measure of Netflix

[Commentary] Netflix has long treated viewership data on particular titles as something close to a state secret, or at least a trade secret, to the point that it purportedly declines to share that information even with the creatives behind its original series. So my guess would be that it’s not thrilled with Nielsen’s snooping. Especially so since whatever numbers Nielsen comes up with will be incomplete by definition since Nielsen can’t track mobile viewing -- a growing share of total Netflix viewing -- and could therefore be misleading.
