Indeed. It is a pretty darned big deal to be able to see someone who is “like me” being depicted in media. When advertising (and media, in general) was almost entirely depicting white heterosexuals, a significant percentage of Americans weren’t being included in those depictions.
Being more inclusive of ethnicity, sexuality, and ability means that advertising is starting to reflect all of their audience, not just the straight white folks.
And, yes, sometimes it feels ham-handed (like the ads with a group of women, where there’ll be one black woman, one disabled woman, etc.), but I think, on the whole, it’s still far better than it was before.
