Last week, according to Nielsen, 1,053,393 single, adult women tuned-in to a Philadelphia radio station.  This is 91.1% of every consumer who fits this description.

Why should Delaware Valley small business owners take note of this demographic? A study by investment bank Morgan Stanley finds 41% of working-age women are single. That number is expected to increase to 45% over the next ten years.

The study, called 'Growth of the SHEconomy', indicates that single women outspend the average household in many retail categories. Remarkably, says, Erica Sweeney of MarketingDive, "Women purchase more than half of products traditionally considered 'male' including autos, home improvement products, and consumer electronics."

Is advertising on the radio just a day job for Delaware Valley small business owners?  

Thousands of local companies depend on radio advertising to market their goods and services. But, many of these business owners choose to buy commercials only between 6:00 am and 7:00 pm.  Is this a good idea? Maybe not.  Here are the facts.

Last week, for instance, 3,830,493 adult consumers tuned-in to their favorite Philadelphia radio stations. This is significantly higher than the number that tuned-in to a local TV station, read a local newspaper, logged-on to social media sites like Facebook, or streamed audio from Pandora and Spotify.

But radio listeners do not roll-up their ears just because the sunsets. According to Nielsen, 61% of Delaware Valley consumers who listen to the radio during daylight hours, also tune in at night.

Advertising is critical to the success of every Delaware Valley small business owner.  One of the most powerful elements of any advertising campaign is how many people it reaches.

Nielsen, the world's largest consumer insights company, found that advertising reach has a more significant effect on sales than branding, recency, and context.

There are many ways a local business owner can advertise. This includes traditional media like Philadelphia radio, local TV, and newspaper. It also includes online advertising options such as Facebook, Instagram, and Pandora.

They type of customer an individual business needs to reach depends on the goods and services the company sells. For instance, a daycare operator might want to reach households with young children. On the other hand, a real estate agent could be looking for consumers in the market to purchase a new home.

Advertising on Philadelphia radio stations is the best way for small business owners to reach the lucrative, local mother market in the Delaware Valley. Here's why.

Local consumers will spend $93 billion over the next 12 months. Forbes magazine reports that it is moms who control 85% of all household purchases. Locally,  there are more than 583,416 mothers with children under the age of 17 at home.

Delaware Valley small business owners need to pay special attention to these mothers and their wallets. For example, compared to the general population, over the next 12 months, local moms live in households that are

• 32% more likely to get married
• 36% more likely to buy a major appliance
• 39% more likely to purchase carpet/flooring
• 45% more likely to buy a new mattress
• 52% more likely to buy a new vehicle
• 56% more likely to move
• 95% more likely to buy new furniture
• 97% more likely to buy a smartphone
• 101% more likely to refinance a mortgage

Delaware Valley small business owners have  depended on radio advertising to market their goods and services since the first Philadelphia stations began broadcasting in 1922. 

As a matter of fact, the earliest area radio stations were owned by local retailers including Gimbel's, Wanamaker's, Lit Brothers, and Strawbridge & Clothier.

Today, thousands of small business owners still invest in radio advertising. Not only because it's the only local medium that can reach 3,830,493 consumers every week, but, most importantly, because it works.

Meet five of the of local business owners who advertise on Philadelphia radio to capture a significant share of the $93 billion Delaware Valley consumers will spend this year.

Mark Twain has some script writing advice for Delaware Valley small business owners who depend on radio advertising to market their goods and services.

"The difference between the almost right word and the right word is really a large matter - 'tis the difference between the lightning-bug and the lightning," advises Mr. Twain.

In other words, fill your commercials with lightning, not bugs!

Currently, according to the Oxford English Dictionary, there are 171,476 words in the English language. A handful of these words, small business owners can't use in their commercials on Philadelphia radio. The Supreme Court of the United States says so.

Of all the words that can be used in broadcast advertising, however, there is one word that should be shunned: 'get' and all of its nasty derivative forms including 'got' and 'gotten'.  Here's why.

"I wish I had known about radio advertising when we opened up our first store in 1998," says the Dan DiZio the co-founder and CEO of Philly Pretzel Factory. "It would have allowed us to grow even faster than we did."

With permission of his Mom, an 11-year old Mr. DiZio began selling pretzels on the treacherous intersection of Roosevelt Boulevard and Rhawn Street in Northeast Philadelphia. His inventory was remnants from his neighbor, who owned the Kensington Soft Pretzel bakery.

"On the first day I sold 1000 pretzels", recalls Mr. Dizio. "After splitting the profits with my neighbor, I had $100 left in my pocket. A lot of money for an 11-year-old."

Shortly after that, Mr. DiZio began recruiting 40-50 classmates a day to hawk even more pretzels on street corners all over the neighborhood.  This early taste of franchising kept his pockets very full through middle school, high school, and into college.

This was the origin of what, today, is a $50,000,000 a year business with 175 stores in 17 states. Eighty-five of those locations are within 40 miles of Center City Philadelphia. Mr. DiZio has gone from selling 1000 pretzels per day to 175,000,000 per year.

Delaware Valley consumers will spend $98 billion on goods and services over the next year. To claim a significant portion of those expenditures, small business owners need to be at the top of customers' minds when it comes time to buy.

The first radio station in Philadelphia signed on the air 1922.  Since then, thousands of business owners have known, intuitively, that advertising on the medium was a potent way to be remembered when a purchase was imminent. 

As a matter of fact, some of the first Philadelphia radio stations were owned by the Delaware Valley's largest retailers including Gimbel's, and Wanamaker's, 

Today, area business owners no longer need to base their advertising plans on intuition.  Now, there is proof that advertising on Philadelphia radio creates the top of mind awareness necessary to drive sales.

Two things are remarkable about voting day in 1920.  It was the first time, ever, women could participate in the selection of the U.S. President. It was also the first time live election results were broadcast on the radio. Not to mention, it was also the first radio broadcast, ever.

The voters' choice that night was between Warren G. Harding  and James M. Cox.  Both men had derived their political power as successful newspaper publishers.  It is quite ironic, then, that one of these men would reach the highest office in the land on the same night that the nascent radio broadcasting business began its takedown of the newspaper industry.

Nowhere is this takedown more apparent than locally, where radio has become, by far, the advertising medium with the largest reach among Delaware Valley consumers.

"Radio advertising has been instrumental in our growth," says Kristin Smith the controller for Hatfield, Pennsylvania based World Wide Stereo. The iconic Delaware Valley retailer has been selling every imaginable type of home electronics from car stereos to home theatres since 1979.

"Many competitors have come and gone during our 40 years," adds Emily Cole, the company's Director of Marketing. She and Ms. Smith rattle off a long list of names including Tweeter, Silo, HiFi House, Circuit City, and Sixth Avenue.

"Radio has been the one advertising medium we have been using consistently all this time," says Ms. Smith.

Radio is hard-baked into the DNA of World Wide Stereo.  The company's founder and CEO, Bob Cole, first became hooked on electronics as a kid growing up in the 1950s. He remembers building his own radio with some copper wire and the wooden-spool from some sewing thread.
