TV series are not supposedly a new trend, they have long been a part of entertainment history. The main reason people like watching tv series even though there are so many films out there is because they have the suspense that keeps the audience waiting as to what would happen next. It is definitely one of those entertainment media that has indeed stood the test of time.
While there's absolutely nothing against movies, but tv-series produce the same thrill as if we are reading a good book and just want to get to the end of it to know what's going to happen. Even after all these years, many people continue to watch tv series of the past, simply out of nostalgia.
From history, the abc channel is perhaps one of the oldest, giving some super famous tv shows from 1986 until now. We can see Netflix entering the digital scene somewhere in 2013. Now, it is the most popular platform for tv series. Netflix even has its own 'Netflix Originals' and such famous examples can be those of The Crown or Stranger Things.
But that is not the only platform that has been successful with its original series. If you want to get to know more channels and the most popular tv series aired by them, this video by Data is Beautiful features some of the most popular tv series from 1986 to 2019, all arranged in a timeline.
