James Gandolfini’s masterful portrayal of the mob boss with a therapist introduced audiences to the morally complex antihero, paving the way for shows like Breaking Bad and Mad Men.

The Sopranos set a new standard for prestige TV, proving that television could rival cinema in storytelling depth.

9. Rachel Green (Friends)

Her famous hairstyle, dubbed “The Rachel,” became one of the most requested haircuts in history. More importantly, Rachel’s career-driven arc showcased a woman choosing professional ambition alongside romance, influencing how female characters were written in sitcoms.
