Tv commercials promote reverse mortgages. other ads promote medications for high blood pressure, ed, immune system disorders, and high cholesterol. which type of trend do these represent?

Demographic.

Explanation:

Demographic trend is a term that refers to the analysis of population changes over a given period of time. For example, this trend may analyze population growth, the growth of cases of a particular disease, the increase in the number of housing, among others.

We can say that the TV commercials shown above use the democratic trend because they represent what is expanding in society at that time. For example: If there is an increase in the number of mortgages, TV ads will be mortgages. If there is an increase in high blood pressure cases, TV ads will be about high blood pressure medications.
