Tivo Research Analytics Mines Big TV Data

Tivo unit combines viewership data with product sales information to show advertisers which TV shows reach the right consumers.

Twentieth-century department store magnate John Wanamaker famously said, "Half the money I spend on advertising is wasted; the trouble is I don't know which half."

With big-data analysis, it's now possible to know which half is which. Tivo Research and Analytics (TRA) correlates data on television viewing habits to third-party purchasing data to show advertisers which ads are driving more sales, whether it's consumer packaged goods, automobiles or even prescription drugs. TRA is even exploring correlations among television advertising and online advertising so it can help marketers allocate cross-channel campaign spending.

How does TRA do it? It's all in the data, and in TRA's case it's "naturally occurring" data, meaning it's not based on surveys, diaries or logs collected from a small sample of TV viewers. The company's Media TRAnalytics service, launched four and a half years ago, relies on data from cable company set-top boxes to compile actual -- not estimated -- data on what shows are being watched and which ads are being seen in roughly 4.4 million households. Nielsen, by contrast, uses TV viewing data from a panel of some 20,000 households to extrapolate what share of approximately 116 million households are tuning in to particular shows.

Nielsen and TRA are in fundamentally different businesses. Nielsen's ratings tell you how many households are tuning into mainstream broadcast and cable television shows. TRA goes after "the long tail" of smaller networks and programs and it licenses Nielsen data so it can combine and offer both sources to customers who are already subscribers to Nielsen ratings data. More to the point, TRA answers the fundamentally different question: Was my advertising effective in driving increased sales?

"Just knowing what people are watching on television doesn't answer that question," says Mark Lieberman, TRA's CEO. "To do that, we went out and licensed purchase data on what people are buying in places like supermarkets, what cars they're buying and what prescriptions they're filling."

The essence of Media TRAnalytics is correlating TV viewing data with these third-party data sets, and doing so in a way that doesn't raise privacy concerns.

In the case of supermarket purchasing, TRA partners with loyalty card data aggregators Dunnhumby and GFK. More than 80% of supermarket purchases are tied to loyalty card records, and using double-blind matching processes, TRA can correlate TV viewing with consumer packaged goods (CPG) purchases across 40 million households. TRA knows that set-top box "123" belongs to the same household that holds loyalty card "ABC," but no personally identifiable information is held in TRA servers or tied to that insight, according to Lieberman.

With this combination, TRA can tell advertisers which and how many households in which zip codes are heavy purchasers of, say, breakfast cereals, and which brands they're buying. Further, it can tell them which shows these buyers watch and whether ad campaigns run on these programs are stimulating higher sales.

Retailers and consumer package goods companies use these insights in any number of ways. If they're simply trying to increase sales, they can run ads on shows watched by loyal customers. If they're introducing new brands or trying to gain market share, they can run campaigns on shows watched by buyers of rival brands.

The real win -- and the part that addresses Wanamaker's lament -- is that advertisers can track campaign results over time and quickly discover whether their ad investments are paying off.

"What we're doing is telling advertisers which programming is rich in households that have particular purchasing preferences," explains Brian Canning, TRA's chief technology officer. "You can identify which households are known to buy Wheaties, for example, and that are heavy purchasers of cereal in general. Then you can see the rating for every program on television against that universe of households."

Ratings are expressed as an index, so, for example, the show "CSI" might have an index of 120 for Wheaties purchasers -- 20% higher than the average index of 100. Without TRA insight, ad buyers typically purchase based on the gross rating points (GRP) and demographics of any given show. But it could be that when considering two shows with identical GRPs and similar demographics, one show over-indexes for buyers of particular products whereas the other show under-indexes for those buyers.
