The amazing 4th screen!

The 4th screen is mobile communication devices, namely smartphones and tablets. The other 3 screens are the cinema, the television and the game console. The "Location-based services" (LBS) is a kind of information or entertainment service, which can be accessible with mobile devices through the mobile network. It uses information on the geographical position of mobile devices. For example, the location-based games and personalized weather services. And it also includes services to identify a location of a person or an object. What’s more, it has mobile commerce with forms of coupons or advertisement directed at customers based on their current location. "Mobile" connectivity has an important impact on marketing because customers can express their opinions with others easily with smartphones. For example,  if one consumer doesn't feel satisfied a product of a company, then he or she can communicate with some friends through twitter with smartphones which may be a lot of people. In a bad situation, the product may not sell well due to this kind of communication between so many consumers. The 4th screen is a new channel for marketing strategies which is much fast and effective. This is also a good opportunity for marketers. They can easily collect large amount of information of target consumers which can help them to market. Tablets like the iPads are becoming more popular. Because of its convenience and fast speed, many people embraced tablets. However, there are also many people against tablets. I think there are many reasons. The first reason is that many old people don't accept new technology easily. The second reason is that the mobile devices are always very expensive that people cannot afford. Finally, some people think that it will waste a lot time with tablets.
