I like marketing and advertising. It is my job after all.
The problem is that if you want the companies that you take for granted to stay in business, then they have to keep selling things, how do they make sure that people are going to keep buying? Marketing.
Basically any company that doesn't market fails. A lot of people think that if a company already has a good rep then it will sell on that alone, but it's completely false. Companies need to put out new marketing campaigns in cycles, some as fequently as monthly, otherwise their competitors will.
And with the digital age, stuff like this is a brilliant way to market. We do it, and we use all sorts of other digital media to promote ourselves.
