What Is a DMA (Designated Market Area)?
A DMA is a geographic region defined by Nielsen Media Research as the area where households receive the same local TV stations. There are 210 DMAs in the US, ranging from New York (#1, covering ~7 million TV households) to tiny markets of fewer than 50,000 households. When you buy local TV advertising, you're typically buying within one or more DMAs — your ads reach everyone in that geographic footprint who watches that channel.
Why Local TV Works for Regional Businesses
Local TV delivers several advantages over national campaigns and digital advertising. First, local reach is precise — your ad reaches people who can actually visit your business or use your service. Second, local TV hosts and personalities carry community credibility; when the local morning show host endorses your restaurant, viewers trust it in a way they don't with a national ad. Third, local TV is significantly more affordable than national TV, allowing businesses to run campaigns that would be impossible at national rates.
Types of Shows Where Local Brands Advertise
Local morning shows are the single most popular category for SMB advertising — they combine high viewership, trusted hosts, and demo-favorable audiences (homeowners, parents, professionals). Local news programs command the highest ratings in most markets. Cooking and lifestyle shows attract high product purchase intent. Community interest shows (health, home improvement, business) offer niche but engaged audiences. Sports programming delivers the most passionate viewers, though at premium rates.
How to Choose the Right Local TV Show
The best match between brand and show is where audience overlap is highest. A pest control company sponsors a home improvement show. A gym sponsors a morning wellness segment. A car dealership sponsors local sports coverage. Beyond audience match, consider: the show's production quality, the host's reputation in the community, the package options available (spot, segment sponsorship, host read), and whether remote appearances are supported if in-person isn't feasible.
