Background: Bad Robot is a production company by J.J. Abrams that specializes in television programs as well as film.
Logo: In a box containing grey billowing fog and some tall grass, which is situated against a black BG, a silhouette of a robot sneaks the rough the grass at a distance from the right to the left, and then the shabby robot, which is revealed to have a red color scheme, a curved rectangular shaped head with black a neck and metal spring for hair, and yellow eyes, appears in front of us. "BAD ROBOT", in a white abstract font, appears below the box when the robot is revealed. Instantly the picture becomes still.
FX/SFX: The robot moving. Looks like Flash animation.
Music/Sounds: The sounds of rustling grass and the two little kids (actually J.J. Abrams' kids) say the company name. The voice could be heard over ABC's credits music/announcements on BR's shows on that network.
Music/Sounds Variant: On early episodes of Alias (the first show to have this logo in any form), the kids' voice is softer.
Availability: Appears on J.J. Abrams' shows, such as Alias, Lost, What About Brian, and Six Degrees. The last second of the logo appears on the trailer of Cloverfield.
Scare Factor: None to low. This is considered as a humorous logo.
Logo: Same as the movie logo, except the logo is shortened to when the robot appears in full view from the left and the logo fades to a 2D illustration of the image (two logo shots here depict the logo before and after the transformation).
Variant: Starting with Almost Human,after the robot appears the symbols "@" and "_" appears in the company name, makes it read as "@bad_robot".
FX/SFX: The robot moving (this time in CG-reused from the film logo), the fade to the 2D illustration.
Music/Sounds: Same as the first logo.
Availability: Appears on J.J. Abrams' shows, such as Fringe, Undercovers, Alcatraz, Revolution, Person of Interest, Almost Human and Believe. May also appear on later episodes of Lost.
Scare Factor: None to low. The retained voiceclips of the kids saying the company name can still be considered funny, though the CG appearence of the robot may get to some.
