TiVo has announced a new service for advertisers and those interested in tracking commercial viewership, the Top Commercial Rankings reports, which is based on info gleaned using TiVo's StopWatch feature that tracks viewer behavior second-by-second. The feature has TiVo compiling reports for April and May on metrics like the top commercials watched overall (Disturbia and Ford trucks), or the least fast-forwarded campaigns (FedEx and Samsung Jitterbug). The report includes interesting insight into how viewers watch television, even timeshifted programs, and should provide advertisers more information about how to maximize their impact. Now to get this report to studio execs to keep them from blaming DVRs for the downfall of their industry.
