THX Theatre Alignment Program

Background
This was THX's division created in 1983 to ensure quality playback in theaters (specifically ones not THX-certified).

1st Logo (May 19-October 13, 1995)
Visuals: Scrolling in the credits is the text: "Quality assurance services for the release of [movie title] were provided by the THX Theatre Alignment Program. If you experience any conditions that detracted from the theatrical presentation of this film, please call". The THX logo appears next to the TAP logo, where "TAP" is enclosed in a circle saying "THEATRE ALIGNMENT PROGRAM". Under the THX/TAP logos is "1-800-PHONE-THX".

Variant: On Nine Months, it includes "or visit http://www.thx.com on the World Wide Web."

Technique: Scrolling effects.

Audio: Only the music remaining on the end credits.

Availability: It debuted on Die Hard with a Vengeance and seen on Nine Months and Strange Days. It appeared on Casper (text notification only) and Waterworld among other TAP titles, but prints might cut those out. It might've appeared on Apollo 13 as well, but it's removed on most prints.

2nd Logo (February 9-November 22, 1996)
Visuals: Same as the first logo, except the THX logo is in a black box and the text omits "for the release of [movie title]". Under the THX/TAP logo is the text "1-800-PHONE-THX or leave your comments at http://www.thx.com". The logo either scrolls or is still, depending on the film.

Technique: None. Scrolling effects on Broken Arrow and Jingle All the Way.

Audio: Either the music remaining on the end credits or silence.

Availability: It debuted on Broken Arrow, and also appeared on Independence Day, Jingle All the Way, and Chain Reaction. The early/non-HD print of ID4 on TBS/TNT didn't have it as the credits were recreated, but all other prints preserve it, including the current TBS/TNT print with 20th Television's recreated credits.

3rd Logo (November 1, 1996-February 21, 1997)
Visuals: During the closing credits, this text appears: "If you experienced any condition that detracted from the theatrical presentation of this film, please call 1-800-PHONE-THX or visit www.thx.com. Quality assurance services were provided by the THX Theatre Alignment Program." Under the text is the THX/TAP logo.

Variant: On Daylight, the THX/TAP logos are omitted.

Technique: None or scrolling effects.

Audio: Either the music remaining on the end credits or silence.

Availability: It debuted on Romeo + Juliet, and also appeared on the Special Edition versions of Star Wars Episode IV: A New Hope and Star Wars Episode V: The Empire Strikes Back, One Fine Day, and Daylight.

4th Logo (March 7, 1997-June 21, 2002)
Visuals: Same as the '96-'97 version, except that the font and THX/TAP logos are different. The TAP logo now consists of the letters "TAP", with the "A" mostly being cut-out. Below the logo is the following words:

THEATRE ALIGNMENT PROGRAM

Variants:
 * The home video version of the Special Edition version of Star Wars Episode VI: Return of the Jedi omits the text "THX THEATRE ALIGNMENT PROGRAM" and only shows the logo under the text "QUALITY ASSURANCE SERVICES WERE PROVIDED BY THE".
 * Titanic and Anastasia have the 1995 TAP logo instead of the 1997 one.
 * On Minority Report, only the THX and TAP logos are present, and is moved to the center of the screen. This is cut out on most releases; it is only known to appear on the screener VHS and select international home media releases.

Technique: None or scrolling effects.

Audio: Either the music remaining on the end credits or silence.

Availability: It debuted on the Special Edition version of Star Wars Episode VI: Return of the Jedi, and also appeared on Titanic (excluding post-2012 theatrical and in-home releases), Speed 2: Cruise Control, Anastasia, The Thin Red Line, Star Wars Episode I: The Phantom Menace, A.I.: Artificial Intelligence (theatrical prints only; in-home and TV releases omit it), Pearl Harbor (excluding the director's cut), and Minority Report.

5th Logo (early 2000s)
Visuals: On a black background is the TAP logo from before, but in and shining. Underneath is the text "THEATRE ALIGNMENT PROGRAM", stacked on each other and spaced out.

Visuals: During the credits of a broadcast-exclusive Fox movie, the THX (with Lucasfilm byline) and TAP logos are seen. In the next shot is the text: "Quality assurance services were provided by the THX Theatre Alignment Program.
