TV for sure. Think about it, there are many different kinds of peanut butter but how do people decide witch peanut butter they buy. Most people don't talk about peanut butter restaurants yes, but not peanut butter! TV Ads do the best job of getting you to buy there brand of peanut butter, it's seen by all members of your family and have a phrase that sticks with you. Choose mom's choose JIFF. Toilet paper, I'm sure word of mouth works great for that product LOL! But don't squeeze the charmin comes to mind. Here's one for GameznFlix.
"Make the switch to GameznFlix" Netflix is "We Deliver" TV AD's will lead to Word of mouth, hey did you see that on TV?
I heard about them on TV, how is there service? Your getting the cart before the horse, the horse is the TV Ad the cart is where the people talk about it "Word of mouth". Get the TV Ad out there and give the people something to talk about. Have you made the switch to GameznFlix?
