Candidate passages:
While working in the office Lloyd and Levitan were telling stories about their family and they thought that could be a show idea, and started working around the idea of a families being observed in a mockumentary style show.
They then later decided it would be a show about three families and their experiences.
The show was originally called "My American Family".
Originally, the camera crew would be run by a fictitious Dutch filmmaker named Geert Floortje who had lived with Jay's family as a teenage exchange student and developed a crush on Claire (while Mitchell had a crush on him), but decided against it.
The creators pitched it to three of the four major networks (they did not pitch it to Fox due to problems Lloyd had with the network with previous shows).
CBS, not ready to use the single-camera style of filming, nor ready to make another large commitment, did not accept the series.
NBC, already having two shows of similar style (mockumentary), "The Office" and "Parks and Recreation", decided against accepting the series until the success of the other two series decreases.
ABC accepted the series.
The series was given a full season pickup on October 8, 2009.
On January 12, 2010, ABC Entertainment President Stephen McPherson announced that "Modern Family" had been renewed for a second season.

They started working on the idea of a family being observed in a mockumentary-style show.
They later decided that it could be a show about three families and their experiences.
It was originally called "My American Family".
The creators pitched it to the Big Three television networks (they did not pitch it to Fox because of issues Lloyd had with the network over "Back to You").
CBS, which was not ready to use the single-camera style of filming nor ready to make another large commitment, rejected the series.
The network had recently aired "Welcome to The Captain" and "Worst Week", two single-camera sitcoms that lasted only one season (CBS would not attempt another single-camera series until 2013, when it picked up both "We Are Men" and "The Crazy Ones" for its fall lineup; "We Are Men" was cancelled after two episodes).
NBC, already broadcasting "The Office" and "Parks and Recreation", decided against taking on a third mockumentary-style show.

The series quickly became a priority for ABC after the pilot episode tested high with focus groups, resulting in the network ordering 13 episodes and adding it to the 2009–2010 fall lineup days ahead of ABC's official schedule announcement.
The series was given a full season pickup on October 8, 2009.
On January 12, 2010, ABC Entertainment President Stephen McPherson announced that "Modern Family" had been renewed for a second season. 
Fox picked up the series for a 10 episode second season after it was dropped by ABC.
The series creators paid particular attention to focus groups and other sources of criticism.
They changed some of the designs, opting to make Jay Sherman's head rounder and his pupils bigger, introduced a love interest (Alice Tompkins) and generally made Sherman's character less pathetic.
The lower budget also necessitated a clip show episode as one of the 10 from the season.
The series went over as poorly at Fox as it did at ABC.
In the DVD commentary tracks, Al Jean offered several reasons why the show failed on Fox despite promising ratings when put alongside The Simpsons (particularly after the cameo appearances by Jay Sherman on The Simpsons), mainly that the network simply didn't have as much financial interest in the series because they didn't own it.
The Critic was solely owned by Sony, which meant that reruns and syndication deals would not net Fox any money down the road, whereas a 20th Century Fox show like "King of the Hill" would yield profits.
He also suggested that Fox had less invested into the series because it was inherited from another network.
The series was canceled a second time after the second season. 
Creation and conception.
Dan Povenmire and Jeff "Swampy" Marsh had conceived the idea of the "Phineas and Ferb" series while working as layout artists on "The Simpsons."
After planning the basics of the show, the two began laying out characters.
Povenmire, eating dinner with his family at a Wild Thyme restaurant in South Pasadena, California, drew a quick sketch of a "triangle kid."
Povenmire named the triangle doodle "Phineas," saying he "looklike [one", and with reference to the character Phileas Fogg (often misreferenced as "Phineas Fogg") from "Around the World in 80 Days."
(1873) Povenmire tore the paper out and called Marsh that night, telling him "Hey, I think we have our show.
"After designing the show, the two had significant difficulties getting the series green lit.
It was not picked up for fifteen years.
In their final pitch to the Walt Disney Company, the creators designed a recorded storyboard, featuring a very rough outline of characters.
The prototype Phineas was ruder to others than the version in the eventual show, where the creators decided to make him more kind.
Citing comedy's "big duos" including Wallace and Gromit and Jay and Silent Bob, the creators chose to give Phineas most of the dialogue while Ferb remains almost silent.
