Every industry develops narratives that begin as useful simplifications and eventually become accepted truths. Advertising is no different. But the problem is that many of these narratives survive long after the market has stopped validating them.

The industry says streaming television is becoming a performance channel, then acts surprised when television behaves like television and does not provide immediate direct response gratification. Companies position themselves as alternatives to walled gardens while consolidating more of the advertising stack under their own control. Billions of dollars continue flowing into identity infrastructure even as evidence mounts that much of the underlying data is way less accurate than the industry would like to admit.

None of these observations is a secret. Most people reading this have probably witnessed some version of them firsthand. But somewhere between what the industry says and what the market rewards is often where the truth lives.
