I anyone buying newspapers in news stands? Who cares if comic books are sold there?
I buy comics at the local book store. Every Barnes and Nobles I've been to has at least a couple shelves of comics: Trade Paper Backs (TPBs), which are collections of multiple issues that cover a single story line.
I haven't bought single issues in decades, but buy a lot more TPBs than I did back in the 80s. If I want single issues or special orders, I'll go to the local comic store. Every town I've been to has one. My kids are teenagers and mostly read comics in TPBs, as well. They're generally not interested in buying single issues.
A better article would be the metamorphosis of the local Comic Book store. What have they evolved to when there are less casual readers?
Comic Book stores I've been to also do a lot of table top gaming (ie: D&D, Magic The Gathering, etc.), comic-related merch (ie: posters, T-Shirts, etc.), and whatever their communities want. They also will special-order and hold non-comic items (ie: SF/Fantasy novels) for regular customers.
