Of all the advertising options available to Delaware Valley 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 Philadelphia radio stations can reach 266% more consumers than these two streaming-audio platforms combined.

If you don't have time to read this entire article, then I will tell you right now. The best way to advertise in Philadelphia and the Delaware Valley is on Philadelphia radio.

A vital function of advertising is to build mental availability, which nudges a consumer toward the purchase of a product or service. It also serves to provide public notice that a product or service exists and is available for purchase.

Consumers in the Delaware Valley area are expected to spend at least $98 billion at retail this year. To claim a greater share of this giant pool of cash requires local business owners of every size to advertise their goods and services. As Professor Jef Richards at Michigan State University points out, “Advertising is totally unnecessary…unless you want to make money."

It's time to set some misguided Delaware Valley small business owners straight.  When we say everybody listens to Philadelphia radio stations, we mean everybody.  Generations X, Y, and Z. Baby boomers, and, yes, the millennial generation.

You know...millennials. Those are the "kids" who came of age at the turn of the millennium (which is, debatably, either 2000 or 2001).  This means 18-34 year olds. 

In the Delaware Valley, 1,245,444 millennials make-up 29.4% of the adult population and will deliver $32.3 billion to local cash registers.

But here's the thing about millennials that many small business owners get wrong: millennials listen to the radio.  Almost all of them. 89.8% of them to be exact.
