Usage of "this trend"

In the first paragraph, I introduce a fact that celebrities have become important after the media has started cover their activities. And in the second paragraph, I addressed that fact through "this trend". Please someone tell me whether the usage of that phrase is acceptable or not.

Celebrities have been playing a prominent part in the world especially since the third industrial revolution in which the media took initiatives to disseminate information about famous people. However, many critics conjecture that not only would this trend might pose insidious negative implications for education of young children and adolescents, but it could also lead to an increase in alcohol and tobacco usage among young people.
