Water, electricity, gas, and trash: no, it's not a list of mutant superpowers (because that would mean that the two superheroes with dominion over gas and trash really got the short end of the stick, unless they were supervillains, in which case that's about right). It's a list of some of the most important utilities available to us in our homes and offices. Throw in Internet access, and you've got a fine list of what many people would consider necessities.
Utility companies might not have to do much advertising, since people generally need what they're offering. However, if the company's facing a little bit of competition, or if a company simply wants to earn some goodwill from the public, promo products are a great way to help. Giving out themed stress balls at community events or magnets in direct mail campaigns is a fine way to make a positive impression.
It's not just up to the utility companies themselves to help people learn about the importance of using our utilities responsibly. Schools and government offices alike can get people thinking about the utilities that make life easier every by handing out utility-themed promotional items. So take a look at the items we offer. We're almost sure we can see a light bulb clicking on above your head already!
