That’s what it seems like. Or they have something mixed up. A .3 share? Gotta raise the BS flag on that one.
Keep in mind that they PAID for that .3. Hubbard subscribes, which means they PAY for that listing. If there's any error, they have already called their Nielsen rep, and if there's some error, Nielsen will announce it very quickly. The station has recourse, and they can review all the data if they want. But chances are that the .3 is what they got.
