ABC Studios

Background
In February 2007, Touchstone Television was renamed to ABC Television Studio, which was renamed again to ABC Studios in May 2007; however from 2007 to 2009, Touchstone Television survived as an in-name-only unit of ABC Studios until the conclusion of the final season of Monk. On August 10, 2020, ABC Studios was folded into ABC Signature.

1st Logo (placeholder logo) (May-September 23, 2007)
Logo: On a white background, a black ABC circle (in the 1988-2007 style) iris in on the left with the text "studios" in the same font as the ABC logo, with a shadow effect rises up from the middle of the screen on the right side of the logo.

Technique: 2D animation.

Music/Sounds: None.

Availability: Rare. Appeared on Jimmy Kimmel Live, season 2 of Kyle XY, and some ABC summer programs in 2007.

2nd Logo (Start Here) (September 24, 2007-March 18, 2014)
Logo: On a white/silver background, we see silhouettes of people working in a studio, carrying ladders, cameras, etc. As one of them strikes a clapperboard, we rapidly zoom past the workers into the lens of a camera, which overtakes the screen. There we see the ABC logo, in 3D with a "glossy" texture, with "studios" next to it, in a dark background with a small blue streak passing by, similar to the "Start Here" graphics from the 2007 fall season.

Trivia:
 * The whole logo appears to be a throwback to the 1962 "An ABC Presentation" camera logo.
 * At the beginning of the logo, the numbers 4, 8, 15, and 16 appear on the clapper, then 15 and 16 change to 23 and 42. These are the recurring numbers from Lost. The numbers were also spotted in the September 15-21, 2008 issue of TV Guide Magazine. Plus, you can see the words "WISTERIA LANE" on the bottom of the camera crane, which is a reference to the fictional street from Desperate Housewives. Design-wise, this logo was probably the work of Troika Design Group, who were behind the "Start Here" look.
 * If you look closely at the camera as it moves towards the screen, the film roll attached at the top appears to have a Touchstone thunderbolt on it, likely due to the camera equipment not having had its branding updated to reflect the then-new name and logo at the time that segment was recorded. This is more evident in higher quality copies of the logo.

Variants:
 * Both widescreen and full screen versions exist.
 * There was a variant in November 2008 where Bolt (from the Walt Disney Animation Studios movie of the same name) was shown in the camera lens then barks loudly and looks at the camera. This is to promote the aforementioned movie.
 * On Ringer, there was a short variant where it simply shows the logo in a dark background with a small blue streak passing by from the left to right. Also, some original airings of Lost used a slightly extended version of that.

Technique: Likely live action combined with lighting effects, followed by CGI as the logo appears. The animation for Bolt in his variant is animated by Walt Disney Animation Studios.

Music/Sounds: A bass drum "boom" heard simultaneously with the clapperboard, then an uplifting, 5-note orchestration, mixed with chimes. This was composed by John Debney. The first four notes are from the ABC jingle that been used between 1998 and 2021.

Music/Sounds Variants:
 * There is a longer version of the theme that also lacks the chimes.
 * Sometimes, the end theme of the show plays over this logo or none.
 * The music varied depending on the season for some reason on Castle.
 * On season 1 episodes of Castle (excluding the pilot), only the clap sound of the clapper is heard. This is due to an audio mixing error; the music in the left/right channels of the 5.1 soundtrack is missing, and only the clap in the center channel remains.
 * On seasons 2 and 3 of Castle, the clap sound plays over the music.
 * The clap is omitted on seasons 4 and 5 of Castle.
 * Original network airings along with CBS and The CW airings use their generic themes.
 * On the company's sizzle reel, the music is slightly rearranged with a different clap sound.
 * Bolt's bark in his variant can be heard on the last note of the fanfare or the generic theme.
 * On The Amazing Race Asia, the last part of the Ugly Betty end credits theme is heard.

Availability: Somewhat uncommon. This logo is no longer used as of September 2013.
 * It's on just about any show produced by ABC before 2013 (i.e. Desperate Housewives, Grey's Anatomy, Scrubs etc.)
 * Since the fall of 2009, this does not appear on original ABC broadcasts of their shows, which have it cut out in favor of an in-credit mention for the studio. VOD and home media releases have the logo though.
 * However, the logo will still be shown on original ABC airings of shows co-produced with another television studio, like Sony Pictures Television on Happy Endings, or Lionsgate Television on Nashville.
 * It can also be seen on Criminal Minds and Ghost Whisperer on CBS, and other ex-Touchstone shows (except for post-2007 episodes of Monk).
 * A shorter widescreen version was seen on season 2 of Dirt on FX.
 * The version with the music was last seen on Jimmy Kimmel Live! on ABC and Legend of the Seeker in syndication. It still appears on repeats of According to Jim on Laff and Castle in local syndication.
 * It plasters the Touchstone Television logo on ABC.com and Hulu prints of Felicity.
 * This logo does not show up on the 2012 short-lived series Missing.
 * The Bolt variant is extinct and was only seen on airings of shows in November 2008 to promote the film's release.
 * This was used as a de-facto home entertainment logo on DVD and Blu-ray releases of ABC shows beginning in August 2008, replacing the Buena Vista Home Entertainment logo.
 * On season 12-15 episodes of the USA version of The Amazing Race, the CBS Paramount Television or CBS Television Studios logo and this logo didn't appeared, as the two companies produced it.

3rd Logo (September 2013-October 2020)
Logo: A pale yellow spotlight fades in, moving towards the top-right of the screen. It flashes brightly for a moment, and some of its light morphs into the 2013 ABC logo and the word "studios", now in a different font (set in ABC's custom typeface, ABC Modern), written next to it. The word and logo shine and zoom in. The spotlight continues to move towards the corner, gradually fading out.

Variants:
 * Early Variant: The spotlight and tint on the ABC logo are.
 * There is a variant in which the light and ABC Studios logo simply fade and zoom in.
 * An extended variant is used as the home entertainment logo at the beginning of all current DVD/Blu-ray box sets of ABC Studios shows released by Disney.
 * For ABC Studios International, it's the still ABC Studios logo on a black background, with the word "international" below "studios".
 * On Harrow, it appears in-credit over a blue background.

Technique: CGI from Loyalkaspar.

Music/Sounds: A light 6-note synthesized glockenspiel tune, followed by a deep dramatic string note and drum beat, composed by Filip Eisler.

Music/Sounds Variants:
 * Sometimes, the music from the previous logo is heard.
 * Sometimes, the logo is silent.
 * In some cases, only the glockenspiel is heard.
 * Starting with Agent Carter, the theme is slightly slowed-down.
 * Original network airings on ABC, Fox and CBS have a generic theme and a voiceover.
 * An extended version of the theme exists.

Availability: Very common.
 * Appears on all of their shows produced by this company from 2013 until 2020.
 * The standard pale yellow version appears on current episodes of ABC shows, such as Jimmy Kimmel Live! and Betrayal.
 * The red version appeared on early episodes of Marvel's Agents of S.H.I.E.L.D.
 * Again, not on the actual ABC broadcasts of said shows, which have the in-credit mention.
 * Still seen on ABC shows co-produced by another studio, like 20th Century Fox Television on Speechless, Sony Pictures Television on The Good Doctor, or Lionsgate Television on seasons 2-4 of Nashville.
 * The ABC Studios International variant appears on Reef Break and Harrow.
 * Last known new usage was on Jimmy Kimmel Live! in October 2020. As of October 7, Kimmel is now credited to ABC Signature.
 * Like the last logo, this was also used as a de-facto home entertainment logo on ABC DVDs and Blu-rays beginning in 2013.
 * It makes a surprise reappearance on Season 2 of Woke, likely because it was produced before the folding to ABC Signature.
 * On season 23-32 of the USA version of The Amazing Race, the CBS Television Studios or CBS Studios logo and this logo didn't appeared, as the two companies produced it.

4th Logo (September 29, 2013-2020)
