One definition of good advertising is how effectively it reaches the most people and engages its audience for longer periods of time.

According to that definition, placing advertisements on toilet paper rolls is a brilliant move that should “wipe away” competing promotional tactics, correct?

[On the other hand, you might think this advertising idea “stinks.”] 

But it’s just what two young entrepreneurial brothers are up to. They’ve formed a business – Star Toilet Paper – that supplies toilet paper to public bathrooms.  And the TP features advertisements printed right on the roll.

According to brothers Bryan and Jordan Silverman, Star’s toilet paper is made from environmentally friendly materials, with coupons and ads printed on them using a soy-based ink.

Their company sells space on the rolls for a half-penny per ad.  Coupons printed on the TP can be redeemed through the company’s own website.

Reportedly, some big-name advertisers like Ben & Jerry’s ice cream have signed on … as have some smaller businesses like physicians offices.  (No word on whether the doctors specialize in gastroenterological medicine.)

How are the Silverman brothers enticing restaurants, bars and other venues to stock their toilet paper? They’re providing the ad-filled rolls to these establishments at no charge.

Not surprisingly, this idea came to the brothers while they were students in college.

After patenting the concept in 2010, they’ve since formed their company, developed a business plan, and have already lined up approximately 50 advertisers.

How successful is the endeavor so far? No official word on whether the brothers are “cleaning up” in the business and “flush” with cash yet.

But Jordan Silverman notes that bathroom stall visitors are the very definition of a captive audience. “It’s an unmatched active audience. A person looks at the average advertisement for two to five seconds. People will look at ours for a lot longer,” he notes.

One of the customer segments considered to be highly lucrative for the company is movie theaters.

Come to think of it, this newfangled TP would be perfectly suited for the next Star Trek movie.

… You know, the one where the Starship Enterprise circles Uranus and wipes out the Klingons …
