Due to Magnus Carlsen, chess has had a major boost here in Norway. His major tournaments are covered in detail on TV with commentary by chess experts, which makes it quite approachable and exciting to watch. Given the inevitable slow parts of the game, the experts have time to explain the position on the board, and show how the variations can play out etc. They've somehow managed to turn chess into a spectator sport.…
I've been watching high class matches on TV all my life, but usually with sound turned off. Comments are usually just computer analysis read out loud and background trivia like "he played similarly 2 years ago against XY" don't provide any benefit to me.
The coverages usually consist of a panel with a chess expert and a professional commentator/host, and then various other guests swapped each day. Mostly one celebrity and one other chess player. Then when a move is made it's discussed for some time and variants shown (not just computer analysis read out loud....), mostly by the professionals not looking at a computer. And then the guests can ask noob questions that's also what we viewers are wondering about ("why not just do X") and the chess experts show why.
Then it may be twenty minutes to the next move, so the discussion becomes like a chess-focused talk-show for some time until the next move is made. Or if it's speed chess, that kind of talk is in the 15-20 minutes between each game.
I'm actually going to miss having the speed chess world championship this christmas. Almost become a tradition watching that with the family.
