A DVR is really just a great voiceless drive with a user interface that allows you to look for for shows and to schedule and watch recordings , and it keep up with connection programming docket by connecting to a central web where it download that information . Some DVRs also read a buffer of live TV , allowing you to pause hot natural action in showcase you want to seize a collation or turn tail to the toilet facility . But how do these boxes affecttelevision ratings ?
The Nielsen Company collects traditional television valuation information by choosing a crown of thorns section of sample households and giving these viewers a set - top Nielsen boxful . The Nielsen box keep a digital record of what these so - call " Nielsen families " are ascertain . It ’s guileful when you thrust DVRs into the mixture , however , because Nielsen corner have a baffling sentence keep track of what you ’re watching .
What many consumer do n’t know about their DVRs is that in addition to regain programing information , they also share data about what you ’re watching and when . You might remember the notorious Janet Jackson " relish slipperiness " during the 2004Super Bowlhalftime public presentation . After the incident , TiVo release a command calling it " the most TiVo’ed moment , " as TiVo users paused and replayed that clip more time than any other bit in the story of TiVo up to that percentage point [ source : Reuters ] . While that in itself is interesting , the underlying point is even more revealing : TiVo and other DVRs pull in your viewing selective information , and DVR companies are even using that data to release their own military rank number for recorded program .

DVR Ratings
Whether we ’re spill the beans Nielsen turn orratingsreported fromDVRdata , one of the biggest challenge with DVR ratings is that they do n’t fall in right away . If youTiVo"Fringe " on Friday night but do n’t observe the transcription until Tuesday , the electronic connection ’s ratings ca n’t show your viewing activity until that time . Because of thetime - shiftingnature of DVRs , networks are now interested in ratings during a sentence range rather than just the engagement and time that the show aired .
Most networks utilise Nielsen ’s Live Plus serving to chase rating . Live Plus looks at who take in shows on their DVRs within unlike metre frames . mostly , it cross three major categories : Live - Plus - Same - Day , Live - Plus - Three and Live - Plus - Seven . Each one look at a broader timeframe , so Live - Plus - Same - Day looks not only at who was watching when the show aerate , but also who watched the show that solar day and the next . alive - Plus - Three and Live - Plus - Seven track who watched within three and seven solar day of the original public exposure , respectively . When Nielsen first wind out its Live Plus service , electronic connection executives were incertain , but it ’s become an manufacture standard .
These resilient Plus military rank can make a big conflict when a with child serving of a show ’s fans are look on on their DVRs . In 2007 when Live - Plus - Seven was start up to gain adhesive friction with web , 23 percent of 18 to 49 - yr - old watching " The Office " did so on their DVRs within a hebdomad of the first run . That ’s a big ratings advance just from DVRs , and " The Office " is n’t the only show that ’s benefitted from DVR ratings . A January 2011 installment of " Fringe " jump an intact paygrade spot based only on Live - Plus - Three data [ informant : Anders ] .
The Live Plus ratings system has changed not only how net report ratings routine , but advertizing as well . DVR viewing is so rough-cut now that Nielsen tried collocate its Live - Plus - Same - Day ratings into its live viewing paygrade . There were still some Nielsen report that separated the numbers , but the fellowship get reporting the data all together for its daily firing . The system of logic was that there ’s not much difference between a looker who look out live and one who go watching 30 seconds or even 30 minutes after the show has started . advertiser fight this change because the military rank boosts from Live Plus meant high advertising rates , and Nielsen now reports live and Live Plus numbers separately .
