Nielsen overestimates streaming viewership at the expense of traditional TV, says Mark Marshall, chairman of global advertising and partnerships at Nielsen client
NBCUniversal, The Wall Street Journal reports. “Every media company is valued on a multiple of something, right?” Marshall comments. “The baseline
for all of these is revenue, and if that revenue is understated due to incorrect measurement, then absolutely, the valuations of these media companies are being impacted. That is why a change needs to
happen.”
