Another example of Nielsen not splitting a county that could have easily been split is Polk County, FL, as the entire county is assigned to the Tampa DMA despite the northeast portion of the county being catered more toward Disney (Orlando DMA). In fact, the community of Poinciana is split between two counties, two DMAs, and two school districts (in FL, school district boundaries follow county lines to a T). I've spent the last month in the Lake Wales area and on radio, both Tampa and Orlando stations are receivable well.
