OK this is some curiosity. Maybe some die hard hockey fans who watch both ice and field hockey.
Just to clarify Field Hockey is NOT one of the popular sport in India in the last 2 decades. In most websites they may still write Field Hockey but no there is nothing like popularity.
The sport is popular in Punjab, Haryana, 2 small northern states, then Odisha, Delhi, Jharkhand , and few other cities including Bangalore. Rest most people only know that hockey is about hitting the ball in the goal with a hockey stick . I never played or watched the sport in person , its played in very few schools and colleges except for those places. Don't remember the last time the last time there was a district level competition in field hockey in my district, even netball, ballbadminton, squash, tennikoit , throwball has those events here.
Now coming to how much hockey is shown on TV. For the youth to be interested there needs to be something shown. Despite 15 odd sports channels hockey is shown during world cups, world juniors , asia cup apart from multi sport games ( Indian matches only with the FIH commentators ) on 1 channel, if there is something live in other sports like a cricket match or EPL the sport won't be shown at all on TV instead those same sports may be shown in multiple channels with multiple languages commentary.
There will be streaming of it online but I won't waste my money on subscription for field hockey, let me be honest, I don't like the sport that much, lost the interest over the years and despite the highs of Tokyo I'm more than comfortable with watching it during multi sport events only.
The only sports that you can watch on Indian TV regularly is Cricket, Badminton, Kabaddi , Football, Tennis, Motor Sports, WWE (Nope, no athletics either)
Don't even talk about this sport there . Since Imran Khan came to power the sport has died as he has cut the funding. The players are now part timers who practice only before tournaments . Don't ask if the sport is shown on their TV or apps, non existent.
