How the ways of advertisement have evolved in 30 years’ time

Last week, we talked about advertising ethics and how Sony was stupidly enough to come up with the racially controversy print ad for its black and white PSP. I found it very interesting to see how the opinion has changed and made certain ads impossible today. However, is the “good old days” with the upscale world of Mad Men with sexism and racism really far removed from our lives today? Or has it just changs to the different format and reappears? At least, in my opinion, some of the sexist or lets say sex-related ads still exist nowadays.

Here are some old ads that existing decades ago and also some new ones, it is interesting to see how much it has / has not changed:

So what do you all think? Is a paradigm shift needed to avoid the sexism in the ads, or is it something unavoidable as an effective advertising strategy to attract consumers?
