Here is my correction and I hope it helps you.

We are in the Internet and communications age. Our current technological level allows information to travel rapidly around the world. It can then be displayed on many devices, such as TVs, smartphones, or computers. This, together with capitalism as the predominant economic system, leads to a world where advertising plays a key role in our daily lives.

First, I will discuss the positive aspects advertising offers. I support ads that show me something new. If it weren’t for advertising, I would not have discovered some video games that I have really enjoyed playing. I am thankful  I saw  the advertisement for the new Tesla shop in Madrid, since I then had the opportunity to visit  and see their modern cars. Advertising has been valuable to me, because it has given me a chance to experience new things I would have missed out on otherwise.

On the other hand, I see negative aspects to advertising as well. The first one I see is the   manipulation some ads try to achieve. The cola drink ads, for instance,  which show lots of happy people laughing while holding  a bottle of cola. I strongly believe that the ad  aims to convince us  that happiness and cola go together. Moreover, this strategy  is used again and again in ads for cookies, cars,  and prescription medicines as well. Another negative aspect comes to  mind when I think about  typical infomercials. The main purpose is to sell trendy gadgets which often  break after a few uses and which don’t work as advertised.

In conclusion, I can see  both the advantages and disadvantages of advertising in our lives. I usually try to be skeptical when I am watching an ad, in order to avoid any kind of manipulation. Everyone should carefully analyze any purchase to determine what  they actually need. By doing so, we will be more responsible consumers and only buy what is truly needed.
