How has social media helped evolve the role of the audience in commercial advertisement? Is this a negative thing?

As the social media evolved throughout the years, its range of target audiences has extended by far and now is able to directly address different genders with specific targeted information. There have been ways created in order to discover the most products or other things that are appropriate for gender ethnicity and age. One could be any person out of the blue, and still find one’s self addressed in those advertisements. The use of characters value has a negative effect on genders such as women being objectified and degraded and men being stereotyped and given sky high expectations. Those set boundaries for the youth viewing those advertisements on regular bases. Also another aspect would be how consumers as a youth these days subconsciously advertise products that they have "liked ages ago" but are still contributing to the betterment of the business market.
