The Commercialization of the Network

Internet in our days is becoming very important tool day by day. Through the technological improvements we are now able to buy or sell things through internet. Sites such as Amazon or Ebay can offer us a huge variety of products. I believe that the commercialization of the network give us the oppurtunity to make purchases independently from our home or country. Moreover, it gives us the opportunity of comparing prices, searching for the latest models. Companies have seen the big profit which exists in internet and they have already moved in this era. For that reason we have all these ads or pop ups in our computers advertising hundrents of products. The problem is i believe for the customer. How is possible to minimize as much as possible the number of stupid ads that he receive but on the same time to buy the things that he wants from internet?
