Advertising formed a common practice among our ancestors, which appeared right after commerce was developed and popularized. Not surprisingly, the very same advertising practice, albeit in a slightly different form, still constitutes a frequently practiced behaviour, especially among enterprises and businessmen, now a days.
With the course of time, however, the advertising methods have evolved, for the most part, in more and more sophisticated ones. While not-so-long time ago outdoor advertising was a common marketing process, it has been in a large part replaced by modern technologies.
This type of advertising was pretty simple - usually it consisted of grabbing the potential customers' attention through a poster or a billboard with the intention of persuading them of some idea. Modern advertising has caused a complete revolution in this system. This revolution has as its foreground the use of digital technologies - flashing billboards, multimedia, giant screens - with the purpose of not only grabbing the customers attention and convincing them of some concept, but doing so through entertainment, amusement and interaction with this proto-customer.
Advertising agencies are tremendously delighted about their achievements in this sector of business, and indubitably will continue to innovate it with their inventions.
The "potential customers" point of view, that is, the belief sustained by the people the advertisements are trying to target, and those who they are not, is utterly different, however. While the outdoor variants of the se advertisements were seen by these as a pointless visual containation prone to be ignored, digital advertising is a far more complex issue. Not only it is an unwanted and undesired practice, which drains peoples valuable time and natural resources such as energy, but it also ocassions damage to vulnerable sectors of the population, such as children.
In my belief, which is based on the above affirmations, advertising constitutes and important field of commerce, and it has always constituted it, and thus is cannot be eliminated.
It's toll on the environment, however, as well as the psychological damage it could cause to vulnerable persons, should be put under strict vigilance, and some kind of control should be launched for this purpose.
