Greg Costikyan writes a rather good summary (per 1996) here: A Farewell to Hexes
Since then, hex & counter wargames have managed to stay alive, though no longer at the levels they once were. Incredibly, they have also managed to attract new blood. I'm a hex & counter wargamer, and I only started playing them in the last 2-3 years.
The last few years have been very good for introductory hex & counter wargames. GMT Games is the most influential publisher of wargames currently publishing, and their stand-out hit has been Combat Commander: Europe, which uses a deck of special cards to guide your actions: the cards have Fire, Move, Advance, Artillery and other actions on them, plus reactions as well. It's very approachable and a lot of fun. (Games take 90-120 minutes).
Even newer, and very well regarded, is Confict of Heroes: Awakening the Bear which is even better as an introductory hex & counter wargame.
Still being published is that massive game of Advanced Squad Leader (ASL). MMP (who have the rights to make it) have been struggling to keep the core sets in stock, so it's still selling pretty well and is still being played. It's been getting a lot of new players thanks to the line of Starter Kits. They're still more complicated than either of the previous games I've mentioned, but they've been helping new people (like me) enter the ASL fold.
If you follow the links, you'll find yourself on boardgamegeek.com; I have several session reports (with photos) there for each of the games mentioned if you'd like to see what they look like.
Cheers!
That's about the right of it. Except I would proffer that tabletop wargaming is less prevalent because there are now so many other types of tabletop games and also so many of each. As MerricB points out, there's still plenty of tabletop hex wargaming. If you are in the area (anyone), stop by Games Plus on the night of their four day (twice annual) auction when they have Historical Wargames (Friday) up for bid and also check out the vast array of wargames (hex included) that they have in store. The people who claim the hobby is dead simply aren't paying attention and don't know chit.
