The buying power of Black consumers in the Las Vegas Area is now $6.5 billion. Over the past 19 years, according to Nielsen, the pace of spending by African Americans has grown 28% faster than by White consumers.

If a Clark County small business owner would like to earn a larger share of this spending, the best place to start is with advertising.

"For African American consumers, advertising of all types is an important touchpoint in their shopping journey," says a recent study by Nielsen. "African American consumers are more likely than the total population to agree that advertising provides them with meaningful information about the product use of other consumers."

"African Americans are avid media consumers, across multiple media channels, which gives advertisers ample opportunities to connect with them."

The best advertising medium, though, for small business owners to reach the Vegas African American consumers is local radio.

Almost 442,000 adult consumers in Clark County belong to a fitness club. These memberships bring in close to $820-million in sales to local gym owners.

January is critical for the small business owners that operate gyms in the Las Vegas area. According to the International Health, Racquet, and Sportsclub Association, this one month alone, accounts for 10.8% of annual membership sales. New Year's resolutions are the reason for this early year spike.

To capture a larger share of the $88.6-million local consumers  will spend on gym memberships in January, requires fitness center owners to advertise. The best way to do this is on Las Vegas radio. Here's why.

Of all the advertising options available to Las Vegas small business owners, streaming audio services like Pandora and Spotify are the least effective.  Here's why.

According to Nielsen, after the content of a commercial is considered, the element of an advertising campaign that drives sales the most is reach. In other words, making sure the most people possible are exposed to the advertiser's message is crucial.

When it comes to achieving reach among consumers, Pandora and Spotify rank dead last.  Advertising on Las Vegas radio stations, actually, can reach 235% more consumers than these two streaming-audio platforms combined.

It may surprise many small business owners that Las Vegas radio stations have a larger reach than Pandora and Spotify even among millennials.  Clearly, it is a myth that younger consumers are ditching legacy media in favor of digital options.
