You've done the research. You now know that by every measure, radio advertising is the most effective way for your Las Vegas small business to market its goods and services.

You have learned, for instance, 1,502,898 consumers regularly tune-in to their favorite Las Vegas radio stations.  That's more than 90% of all adults.

You've also learned that, on average, adults spend almost two hours per day listening to Las Vegas radio.

If you dug deep enough, then you know radio advertising delivers, on average, a $10 lift in sales for every $1 invested. This is a remarkable ROI for any Las Vegas small business owner.

What you may not have figured out, however, is what is the best time of day to advertise on Las Vegas radio?

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.

On November 1, 1940, KENO signed on as the first radio station in Las Vegas, Nevada. Since then, local business owners have depended on radio advertising to successfully market their goods and service.

Using any advertising metric, despite the inundation of new media options, radio remains the most potent medium for fulfilling the marketing objectives of Las Vegas area business owners of every size.

If you were one of the 1,502,898 adults who tuned-in to a Las Vegas radio station last week, you probably heard a commercial for the Panda Law Firm (aka Peters & Associates).

"Advertising on Las Vegas radio stations has been an integral part of the firm's growth," says Scott Chatley who has been handling the marketing for Panda law since 2010. "We bought our first radio commercial in 2011 and have been on the air ever since."

Market research affirms Mr. Chatley's use of radio advertising to expand the firm's caseload.

Each week, Las Vegas radio stations reach significantly more local consumers who are likely to hire an attorney than are reached by local TV, local newspapers, or streaming audio sites such as Pandora and Spotify.

If you were one of the 1,502,898 adult consumers who tuned-in to a Las Vegas radio station last week, then you, no doubt, heard Aaron Taylor. You know, 'The Real Estate Guy'.

"Radio, by far, is my biggest source of advertising," says Mr. Taylor. "We have sold more homes and made more money since I started advertising on the radio than I have at any other time before then."

Mr. Taylor had been a very successful real estate agent prior to advertising on Las Vegas radio stations. He established O48 Realty in 2003 and quickly expanded to 116 agents.

"In 2008, I lost everything," says Mr. Taylor. "When the real estate crash happened, I wasn't prepared. The company's expenses were far greater than what little money was coming in."

"I needed a home run to turn the business around. A base hit would not do," says Mr. Taylor, who is very fond of sports analogies. "Advertising on Las Vegas radio was a home run."
