Ithink that it can hav advantages and disadvantages but for the people that always search in internet, it has a lot of disadvantages.
On the one hand, we can say that online advertising is interesting, because you can be surfing in internet and adverts appear in your screen. If you are interested in this advertising, you can visit the web. Otherwise, you can ignore these window.
But on the other hand, advertising sometimes contains virus and if you click on adverts, your computer can be infected.
In my opinion the sponsor of this online advertising spends much money in this and many people are not interested.
