Ask any Las Vegas small business owner how to measure the success of an advertising campaign. The answer will almost always 'sales.'

According to Nielsen research, the media-element of a campaign that has the most significant effect on sales is reach. This is the number of different people exposed to the advertiser's message.

There are more ways than ever to advertise. But, which of those options has the largest reach among Clark County consumers?

Doug Schoen, an advertising professional with 35 years of experience, writes in Forbes: "You wouldn’t know it from all the media coverage focused on streaming video and streaming music, but radio actually has the most reach among American media consumers. 93% of adults listen to the radio each week as compared to 87% who watch TV, a substantive difference."

By April 15th next year, 885,929 residents in the Las Vegas area will file a tax return.  More than 53% of these returns will be completed by the taxpayer themselves, either by hand or with the help of an online provider like Turbotax.

Every season, Clark County small business owners who specialize in tax preparation services lose customers to the do-it-yourself options.  This year, 412,00 local consumers will spend $79,600,000 with tax professionals. But, based on the average cost of services, more than $91,000,000 will stay in the wallets of the DIY crowd.

To clawback this enormous amount of money from the DIY market, local tax services will need to advertise the valuable benefits of using a professional.

The best advertising option for tax professionals is on Las Vegas radio stations. Here's why.

Las Vegas shoppers are expected to spend $5 billion this holiday season.  This will be approximately 4% higher than last year. These estimates are based on forecasts by the National Retail Federation and Deloitte.

To claim a fair share of the Christmas cash, local small business owners will need to battle some giant competitors. Advertising on Las Vegas radio stations may be the perfect weapon to ensure success.

According to information published in the retail trade magazine Chain Store Age, as of right now, here is where consumers are planning to shop...

Las Vegas small businesses that sell products or services to pet owners should sit up and take notice.  Local consumers will spend $465,000,000 this year on behalf of Fido and Fluffy. This amount has increased 323% since 1994, with no sign of letting up.

According to the American Pet Products Association, here's how local spending on furry companions breaks down:

• Food: $190,897,000
• Supplies/OTC Medicine: $102,432,000
• Vet Care: $116,400,000
• Live Pet Purchases: $13,968000
• Other Services: $41,904,000

The biggest month for sales of pet-related products and services in Las Vegas is, by far, December. That is when 10.5% of all annual spending happens in this category.

Las Vegas small business owners have depended on radio advertising to market their goods and services since 1941.  That's when the Laura Belle and her husband Maxwell Kelch put the first successful local radio station, KENO on the air.

Today, there are 35 radio stations that serve Clark County. Each provides a unique blend of music, information, and entertainment.  Some stations focus on politics or sports. Some play country music. Some play the hits. Some play classic rock. Some are on the AM dial. Some are on FM.

When KENO began broadcasting, there were no TV stations in Las Vegas. Those would come 13 years later. Also, there was no social media, YouTube, Sirius/XM, Pandora, Spotify, or smartphones. Each of those would be products of a new Millenium.

With an overabundance of advertising options now available to small business owners, does advertising on Las Vegas radio still make sense?  Here are five facts that serve to answer that question.

Las Vegas consumers are expected to spend $45.6 billion at retail this year, according to Nielsen. This means that every household, on average, will be paying out $55,451.

To capture a larger share of these dollars, local small business owners need to know the answer to two questions.

The first question is, where is this enormous amount of cash being spent?  The list below details the answer.
