John Wanamaker (1838-1922) was a very successful United States merchant, religious leader and political figure, considered by some to be a "pioneer in marketing”. He opened one of the first and most successful department stores in the United States, which grew to 16 stores and eventually became part of Macy’s.

He is credited with coining the phrase “Half the money I spend on advertising is wasted; the trouble is I don't know which half”.

my 2 cts : there was never a culture of performance in marketing. Its very hard, especially in a phygital scenario (digital ad, real world spending)

That's a great excuse for 1830 but today i would expect to see tens of precise , large scale studies from an industry that spends billions every year. The fact that I don't, makes me suspicious

These studies exist, but tend not to be published. Essentially there's little to no commercial benefit from publishing, so people tend not to.

Like, I would argue that 80-90% of Goog/FB revenue is correlated with sales. This may be done badly (often), but it is done.

So how do advertisers find out who has the most effective ad system if they re not getting published? They choose in the dark?
