Phones are not anymore used only to call, nowadays the cellphones have many uses, and the call has become old fashion.
Companies are getting used to all this new technologies and trends, that why every time more we are able to see different kind of marketing campaigns in all different of media, while TV commercials are becoming less effective, as they don’t impact as much as before.
Moreover, all the media is interconnected, phones, social media, commercials, shops… For example, you can go to a shop and in this shop the seller gives you a pamphlet where you can find the Facebook address and also you can find the QR code and enter to the website with your phone. Therefore, companies can reach you everywhere and can send you all the information they want at any point
A good campaign that shows this interconnection is the one that Diesel did. The customer entered to the store to try on jeans and there was a little cartel with the QR code in every model of jeans, so the customer could scan with his/her phone the QR code and “tell his/her friend” that they like those jeans through Facebook (as the QR code was linked to facebook). In this case, if you “liked” a product, you got a discount on it, which seems like a fair exchange for basically advertising the item to all your Facebook friends.
