Last, but certainly not least, Let’s move on to the dramas that have been aired on some of cable television networks. Just like the previous Korean dramas that were released in public broadcast, some of these dramas also received a lot of attention, although their ratings overall tend to be lower than those released on the public networks.

Why is that the case? How do dramas on cable television get fewer viewers than those in public broadcast? One of the reasons is that people mostly watched the dramas on the public channels, which have been going on for a long time. Through public channels such as SBS, KBS, and MBC, people didn’t have to use another additional device to watch a show, which means that the public broadcast shows generally have more viewers.

Meanwhile, the dramas which are released on cable television also have fewer viewers because people have to pay for cable television, such as tvN, JTBC, and OCN. Cable dramas also generally have fewer episodes, such as 10-15 episodes, as opposed to having dozens.

Here are some of the highest-rated Korean Drama from cable television!
