Nielsen Unveils Streaming Ratings for ‘Orange is the New Black,’ ‘Seinfeld’

Nielsen is only tracking streaming data for TV studios that “opt in” — they can ask for information on any shows or individual episodes for particular timeframes. Studios provide audio files of their programs and Nielsen employs audio fingerprinting technology in its panel of 40,000 U.S. homes to measure viewing. – Amol Sharma, The Wall Street Journal
