Doogie Howser, M.D. (1989-1993), is a television comedy-drama starring Neil Patrick Harris as a brilliant teenage doctor who was also faced with the problems of being a normal teenager, despite having graduated from Princeton University at age 10. Created by Steven Bochco and David E. Kelley, the weekly, half-hour "dramedy" Doogie Howser, M.D. starred Neil Patrick Harris as Douglas "Doogie" Howser, a child prodigy who after completing high school in nine weeks, graduating from Princeton at age 10 and finishing medical school four years later, became at the tender age of 14 the youngest practising physician in the country. The show was set in Los Angeles, California and ran for four years on ABC. The soundtrack of the series is by Mike Post and uses Post's trademark mid to late 1980s Yamaha DX-7 synthesizer.

Trademarks of the show include Doogie's best friend, the fast-talking and mischievous Vinnie Delpino, played by Max Casella, climbing in through his window, and Doogie writing in his diary on his computer at the end of each episode.

The show characterized the genius Howser as a normal teenager, rather than having the stereotypical traits of TV "nerds" like Screech Powers (from Saved by the Bell) or Steve Urkel (from Family Matters). Steven Bochco revealed that the show's cancellation came abruptly at the hands of ABC executives--before he and the show's staff had a chance to complete the story line.

A teenaged genius deals with the usual problems of growing up: having a girlfriend, going to parties, hanging out with his best friend, all this on top of being a licensed physician in a difficult residency program. Written by Phil Fernando

Doogie is no ordinary teenager, he is a doctor. As smart as they come, he has been a doctor since the age of fourteen. But it's not because you are highly intelligent that you don't have the same feelings toward life. He is constantly torn between a life of teenage fun with his buddy Vinny, and a more serious and quiet life practicing medicine. Written by Steve Richer
