"Parenthood," an American comedy-drama TV series developed by Jason Katims, premiered on March 2, 2010. It is loosely based on the 1989 film of the same title. It is also the second adaptation of the film to air on television preceded by the 1990-91 television series which also aired on NBC.

After Jason Katims came up with the idea, he approached Ron Howard and Brian Grazer about creating an updated, modern adaptation of the 1989 film and bringing it to television. Production began in 2009 with Katims working as the lead writer, showrunner, and executive producer.

"Parenthood" airs Thursdays at 10 p.m. ET on NBC. Watch a preview below:
