With the development of means of communication from the 1800s until nowadays, all sectors have been developed: communication between people by cellphones or the internet, news and sciences now accessible to all, but most of all culture and entertainment. Society is changing and what used to be theater and literature are getting replaced by film and television, on a worldwide scale. North and South America and Asia are emerging and gaining more and more power. From 1914 to 1975 the United States became the leading economic power, and the culture of this country had soon taken over all the Western world. Major American film industries invaded our big and small screens with successful series and big movies. Today whatever we see on TV is marked by this media empire. Currently, most of the programs that are programmed on our channels are American or Canadian. Some of them: NCIS, CSI, Bones... And it is through those shows that a part of the population developted an interest in criminology, forensic science and more generally in chemistry. This interest in current entertainment is more massive than the one people had in the past entertainments (theatre, literature) before in so far as this field is becoming extent and popularized. Affirming every family in England is in possession of a television might not be untrue. So a huge part of the population is discovering a field, although it is not representative of reality, which he had no access before: forensics.First, this vision of the police science highlights another aspect and this can promote the creation of work in this field.
And last but not least, people realize that for better investigation's results, scientific research is essential, which can lead to investment in this area and anyway it will always augment ways to improve certain techniques such as the detection of blood.
