I wonder if there is any data around effectiveness of targeted advertising. How many lipsticks were sold before social-data-backed target advertising? How many lipsticks have been sold now that we know which shades and "influencers" a particular person prefers? I guess I could go search for it.

You would have to imagine there would be an uptick. However, in my own mind, the targeted ads don't influence me to spend as much money as the broad-based brand awareness type. There's a term for that style of advertising which I can't remember right now but it basically entails plastering "Tide" over everything so that the next time you think of detergent, you think of Tide.
