Which show opened the door to American dramas for you?

The first American TV series I watched was "Friends", which is a classic among American TV series. In my heart, all American TV series cannot surpass its place in my heart. This is a sitcom that tells the life story of six friends in New York. They have spent ten years together and accompanied each other. Monica who has obsessive-compulsive disorder, Rachel who lives independently as a rich girl, quirky Phebe, nerd Ross, simple-minded Joye, and Chandler who has a dry sense of humor, the six of them are funny and warm together. I first watched this drama to learn English because the script was not difficult to write in English and was highly colloquial. Later, I fell in love with this drama because it showed the kind of ordinary people's lives that were realistic yet warm.
