Andy McStay is an academic writer and researcher who specialises in the area of advertising. He also works as a university lecturer.
McStay discusses how advertising works in the modern era. This involves convincing people that they want things that they do not need in order the keep the wheels of consumerism turning. The role of advertising increases in importance during austere times, when people need to be more careful with their money. One way of doing this, which is currently being adopted, is personalised advertising. This means that advertising and search results are tailored to be more appropriate to the user. One one hand, this is convenient, as you will be shown pages that might interest you, as well as there being the possibility of discovering something previously unheard of, such as a new video game or TV series, example. On the other hand, this does have the potential to be unwelcome and frightening. Imagine, if you will, a scenario where a computer is shared between several people. Someone has used the computer to access inappropriate or pornographic material. One day, someone else types lawnmower in to a search engine and... they do not come up with the garden implement. I'll leave you to imagine the consequences. Such a situation has the potential to be quite embarrassing, or so I've heard.
On a more serious note, the idea that advertising can adapt in such a way does scare me, because a time may come when we won't be able to keep secrets from anyone. Big Brother will always be watching us from the search engines.
