Wen it comes to marketing, there are countless ways to advertise. To be heard, to be known, to gather traffic and to earn are one of the targets of companies so their names and products will get into the consumer’s mind. One way to do  this is by using promotional products so your product line will get a little familiar for your audience. For example I am selling a cellphone, a new line of cellphone, then i will use key chains that bears my cellphone’s brand on it then I will give it away to as many people as possible. Now the idea is that the potential customer’s curiosity will their awareness and at some point my product will be known and the product will be bought by the one’s who knew about it. This maybe the lamest example but you’ll get the idea just by looking into the concept.
