Question: The Devil Came on Horseback and The Elephant in the Living Room are both what type of films?
Context: In Western architecture, a living room, also called a lounge room, lounge or sitting room, is a room in a residential house or apartment for relaxing and socializing.  Such a room is sometimes called a front room when it is near the main entrance at the front of the house.  In large formal homes, a sitting room is often a small private living area adjacent to a bedroom, such as the Queen's Sitting Room and the Lincoln Sitting Room of the White House.  The term "living room" was coined in the late 19th or early 20th century. Welcome to My Living Room is a ballad written and sung by Carole King.  It is featured on her 2005 album "The Living Room Tour".  Aside from being a song, "Welcome to My Living Room" is the title to one of Carole King's concert DVDs.  This DVD features songs that were performed during "The Living Room Tour". Live from the Living Room: Volume One is a free digital EP from American rock band, The Format.  It was released in The Living Room, the fan club section of their website, on March 10, 2006.  The inclusion of "Volume One" in the title implies that it was intended to be the first in a series of releases.

The EP also included a bonus video of the Format performing "The Compromise" acoustically at The Knitting Factory in Los Angeles on January 22, 2006.

The Living Room was co-owned by Steve Rosenthal and Jennifer Gilson.  The Living Room has showcased some of the best of New York City’s singer/songwriter, alt-country, and rock.  It moved to Brooklyn in 2015 before closing down in December of the same year.  This music venue has been called "an incubator of talent," and has been described as "a much mellower and tidier successor to CBGB."  Some considered The Living Room as The Bottom Line of the "small bankroll" live rock venues.  Other comparable venues include The Saint in Asbury Park, New Jersey, and The Cellar Door in Georgetown, Washington, D.C..  The Living Room's line up featured four or five singer-songwriters a night, yet the club did not typically charge a cover.  It did have a one drink minimum and a recommended $5 donation for the bands.

The word "ecology" refers to the relationship between an organism and its environment, which may include other organisms.  A device ecology refers to a collection of devices with relationships among each other, that is, these devices can communicate with one another and are aware of each other's presence .  Devices in a future living room, devices in a kitchen, or devices in a factory might collectively form device ecologies (a living room device ecology, a kitchen device ecology, etc.) to cooperatively perform tasks for a user.  Imagine a user introducing a new device to the living room device ecology (i.e., bringing home a new device).  Ideally, the user simply places the device in the living room, and there is an automatic "orientation" of the new device with subsequent integration into the living room device ecology. Jane I.
