Forensic chemistry has become very popular as a field since with the start of TV shows like CSI since 2000. I read an article in 2012 or 2013 that this is one of the top fields of interest for high school students. They watch how forensic chemistry works through these shows and want to join the field.
As others have mentioned before, these shows do exaggerate how forensic science works. There are some technologies and methods on the show that aren't used in reality. But still, I think it's nice that a field that was not really well known or found interesting before has garnered a lot of attention.
