Do Apartment Owners Make Money From Electric And Cable Companies

I was curious to know if apartment complexes make money in other was then just the property itself. I see alot of properties recommend using certain electric companies as well as cable companies. Are they getting a cut of that or is it just a recommendation on both sides.

definately,anytime they recommend a cable company, company to rent washer/dryer from, etc etc,they are getting a referal for it
