What's up with news channel branded stores in Airports?

Factual Questions
1

For example, here’s a Fox News stand at Minneapolis-Saint Paul International Airport.

I’ve been told that there are also CNBC stores in several airports. I assumed that these stores sold junk like t-shirts and coffee mugs with the station logo but I’ve been told that it’s general merchandise like snacks and magazines.

So what is going on here? Are there other channels that due this? Is this just a matter of the channels licensing their logos to these stores? Why would a store want to do this? Why is it only, or mostly, in airports?

News analysts often have books to sell, and travelers are often in need of last-minute reading material. It’s a marriage made in airports.

The chips and candy are just the impulse items that almost every store seems to be stocking at their checkout counters these days.

Apparently USA Today, New York Times, and Sports Illustrated have “stores” too, or at least they did in 2008. The link also talks a bit about why the media companies want to do this (it increases “brand awareness”) and why it’s only in airports (the kind of people these media companies want to reach tend to be frequent travelers.)

Years ago, I was in BWI looking for a Washington Post to read on my flight. I was told that all the magazine stands were owned by the company that also owned the Baltimore Sun and that I wouldn’t be able to buy a Post anywhere in the building.
