I'm not sure those last two are different. You can however split the ad industry surveillance into (at least) two kinds. The first is surveillance aimed at increasing the power of each individual advertisement by personalizing them to the victim, by their nature these typically seek all kinds of deeply personal information about someone's psyche but not necessarily their daily life. The second is surveillance aimed at 'proving' the effectiveness of ads, these typically ignore people's interests but dig deeply into their daily activities, what they buy, what they see, what they hear, just to be able to claim it was their ad that made someone buy something.
