In September 2010, Dark Horse Comics, in partnership with DreamWorks Television and TNT, released the first issue in a four-part digital comic online limited series entitled "Falling Skies".
Written by Paul Tobin with art by Juan Ferreyra, the series details events taking place before season one of the television show, but after the alien invasion and victory.
These issues were later compiled into a single trade paperback volume entitled "Falling Skies Volume 1", which was released June, 2011.
On June 15, 2011, Dark Horse announced that due to higher-than-anticipated orders, the graphic novel had completely sold out.
It remains in publication .
In April 2012, Dark Horse began releasing a second eight-issue limited series entitled "Falling Skies: The Battle of Fitchburg", with Paul Tobin returning as writer and Juan Ferreyra returning as series artist.
The digital comic was made available through both Dark Horse Comics and TNT via their respective websites.
The story takes place chronologically between seasons one and two of the television show, and detail a costly engagement occurring between the skitters and the 2nd Massachusetts Militia Regiment when the aliens surround the human forces at Fitchburg, Massachusetts.
While not vital to the story of the television series, TNT and Dark Horse have stated that "Falling Skies: The Battle of Fitchburg" provides insight into the events leading up to season two, and will elaborate on how the characters got to where they are when the new season opens.
As a companion to the comic, TNT released an audio series featuring the character John Pope, offering additional insight into the events detailed in the comic series. 
Promotion for the season includes a digital comic book, entitled "Falling Skies: The Battle of Fitchburg".
The comic was published by Dark Horse Comics and was launched on April 18, 2012.
Bridging the gap between seasons, the comic picks up where the first season left off.
TNT will launch a Web series titled "2nd Watch" on June 17, 2012 to air after the second season premiere.
Wil Wheaton will host and the series will run for the entire second season of "Falling Skies".
The episodes are available on the "Falling Skies" official website. 
Anne Glass is a fictional character on the TNT television series "Falling Skies" played by Moon Bloodgood.
She is the "de facto" female lead.
"Falling Skies" tells the story of the aftermath of a global invasion by several races of extraterrestrials that neutralizes the world's power grid and technology, quickly destroys the combined militaries of all the world's countries, and apparently kills over 90% of the human population within a few days.
Anne was a pediatrician before the invasion.
She is very inclined towards the civilians, and believes that they should do all they can to help them.
Her husband and son were killed at home in the bombings during the invasion. 
Development officially began in 2009, when TNT announced that it had ordered to pilot an untitled alien invasion project.
"Falling Skies" was created by Robert Rodat, who is best known for writing the Oscar winning film "Saving Private Ryan", which was directed by Steven Spielberg.
Rodat wrote the pilot episode from an idea which was co-conceived by Spielberg.
Originally, "Falling Skies" was called "Concord", referencing the Battles of Lexington and Concord and Tom Mason's profession as a former History Professor.
Spielberg then came up with the title "Falling Skies".
"I felt that this was a very interesting postapocalyptic story with a 21st century on the spirit of '76.
I came up — out of the blue one day — with the name Falling Skies, which is basically what happens to the planet after this invasion.
What is unique about this particular series is that the story starts after a successful conquest of the world," he stated.
Spielberg was attracted to the project due to its themes of survival.
"I've always been interested in how we survive and how resourceful we are as Americans.
How would the survivors feed the children?
How do they resupply themselves militarily in order to defend and even take back what they have lost?"
he added.
Like much of Spielberg's work, such as "The Pacific" and "E.T.
the Extra-Terrestrial", "Falling Skies"' running theme is family and brotherhood.
He explained, "It's a theme I harken back to a lot because it's something I believe in.
It's something I have the closest experience with.
They say write what you know, and with seven children and three sisters...
I tend to always come back to the family as a touchstone for audiences to get into these rather bizarre stories.
"While writing the pilot, Rodat dedicated a five page montage to the alien invasion, but decided not to go through with it as it had been done before in films such as "War of the Worlds".
"I wrote a few drafts of it and I looked at and say, 'Ay-yay-yay, I’ve seen this before.
There’s no emotion to this.
It feels like one of those montages,'" he said.
Rodat came up with the idea of having the children in the series "harnessed by aliens".
"When we were working out the initial stuff, the thing that excited was the idea that adults are killed if they’re a threat, and kids are captured for whatever reason and changed or altered.
The harness was a logical outgrowth of that.
Then what we’ll explore is what the harnessing does to the kid over the course of the show but that also is something that’s going to have to unveil itself gradually," he stated.
Spielberg previously explored the idea of enslaved children in the 1984 film "Indiana Jones and the Temple of Doom".
Series lead Noah Wyle emphasized Spielberg's presence on set by stating "Anytime he gives an anointment to a project, it steps up the pedigree."
Colin Cunningham, who plays outlaw John Pope, exclaimed "You’d show up and think, ‘This is not a TV show; this is something else that we’re doing,’ " he said, noting that Spielberg was very hands-on for the pilot.
"Its scope is massive.
Anytime you hear the word Spielberg, you know it’s not going to be crap; you know it’ll be quality and there will be some money behind it."
Mark Verheiden, who was the showrunner for the first season, stated "It’s great to know you have a world-class filmmaker backing up what you’re trying to do who is supportive and helping design the great stuff."
