How have social media sites and blogs provided new opportunities to deceive and manipulate consumers?

a) They have placed banner ads far more frequently between posts and videos.

b) Looser FTC regulations allow companies to say anything they want about products and services advertised in these new online spaces.

c) They have used influencers and bloggers to create endorsements for their products that do not clearly appear to be ads.

d) The endless information accessible to users of those websites makes viewers much more psychologically vulnerable to ads.
