With the high-correlation between higher income and faster internet connections, it makes complete sense that a high percentage of online-tv viewers are also owner of Luxury Automobiles.

Rising fuel prices have made 2008 a tough year so far for automakers in the US. As they examine every possible method to reach potential buyers, online television may benefit, according to J.D. Power and Associates’ “2008 Power Auto Online Media Study.”

Nearly seven out of 10 new-vehicle buyers surveyed said they went online to find information on TV shows. CNN.com was their top destination, followed by MSNBC and ESPN.

J.D. Power said that buyers of premium-brand vehicles were more likely to look online for TV content than average new-vehicle buyers.
More than three-quarters of buyers of midsize premium utility vehicles, compact premium crossover utility vehicles (CUVs) and midsize premium CUVs said they watched online TV.
