Recently, I've noticed that many dramas started to have a different format. I mean, most dramas used to have like 16-20 episodes with 1h/ep, but now they've reduced the duration to 30min/ep and increased the number of episodes to 30-40. Most of the dramas I'm currently watching and are still on-going, have like 30-40 episodes, and honestly, I was hesitant to start them at first because of this.
I know that it's not a big deal since they still take the same amount of time after all, but I was just curious as why many dramas started to take on this format.
