Procter & Gamble Productions

Background
Procter & Gamble, a consumer products company, entered TV production in 1951 when the soap opera Search for Tomorrow premiered on CBS. As Procter & Gamble is known for their cleaning products, this is where the term "soap opera" came from. They didn't use a logo until 1986.

1st Logo (Early 1986-August 3, 2007)
Visuals: Against a black background, a group of rays in varying shades of rise up from bottom of the screen. The rays form a monolith with a bright, shiny back face, which pans backward (and slightly downward), rotates to face forward, then stops. As it rotates towards the screen, the rays are outlined to make "PGP" in a lined font, which pull into the back of the monolith. The letters shine in a "flash" (similar to the 1978 WGBH logo) and solidify in their color. After that, the words "PROCTER & GAMBLE PRODUCTIONS, INC." (in a white Avant Garde font) appear below "PGP", and are sandwiched by two lines which are formed left-to-right and right-to-left, respectively. This is PGP's first of two proper logos since PGP had no logo per sé until this one debuted.

Date Trivia: This logo made its first end credit appearances on the following Procter & Gamble shows on the following dates in 1986:
 * Another World: late January or early February (on or before February 14)
 * Search for Tomorrow: March or April
 * As the World Turns: April 21
 * Guiding Light: October 13

Variants:
 * There are 2 short versions: one that has the "PGP" drawing then flashing, and another that just has the logo cut to the flash. Both play the same ending.
 * On the 1991 TV movie A Triumph of the Heart: The Ricky Bell Story, "in association with" is below.
 * On at least one December 1986 episode of Search for Tomorrow, the logo simply fades in without the flash effects.
 * On Christmas on Division Street, this logo is still.
 * On A Message from Holly, the logo is still, and is more -ish than.

Technique: Live-action and CGI. According to a comment on this upload, the logo was shot on 35mm film using a 16-axis automated camera stand, programmed using BASIC commands.

Audio: A light, jaunty synth tune consisting of 2 descending bars of 6 notes, then a last bar of 8 notes, then a 4 note sounder, which has a note sequence of A-F#-D-G, as the last bass chord fades away (i.e. just after the rays in the PGP pull back). Generic network promo music was used on CBS starting on August 2, 1999. Sometimes, especially on Guiding Light episodes until 2002, CBS showed the PGP logo twice: first with the normal music, and then with the generic music the second time.

Audio Variants:
 * The most common version just shows the flash and everything after, with the 4-note sounder as the music.
 * On one CTV airing of Another World, the music gets cut off halfway on the last note.
 * Some variants of the logo end with the end credits music.

Availability: Found on episodes of Procter & Gamble soaps from early 1986 to August 3, 2007 like As the World Turns, Guiding Light, Another World, and the final episodes of Search for Tomorrow. This was also seen on other programs co-produced by P&G, such as made-for-TV movies. The long version as mostly used on the soaps' long credit rolls every Friday.

2nd Logo (August 6, 2007-2013)
Visuals: On a white background, a large, globe-like ball zooms onto the screen, diving into the bottom right, leaving a  trail as it does so. The ball, now smaller, comes in from the right side of the screen to form the letters "PGP" (the "PG" is connected) in and aquamarine on its right, and the following text in the same colors below it:

'''PROCTER&GAMBLE PRODUCTIONS,INC.

The ball has a crescent on its right side, perhaps referencing P&G's historic moon logo.

Variant: At the end of the 2011 People's Choice Awards, only the second half of the logo (with the text appearing next to the ball) is shown.

Technique: CGI.

Audio: A light orchestral horn tune with a rising synth sounder, but rarely used because of CBS' tendency to play generic network music over the logo. The version with the logo theme appeared on episodes of As the World Turns and Guiding Light on CBS.com.

Availability: It was used from August 6, 2007 until June 30, 2008 on the soaps As the World Turns and Guiding Light. The logo surprisingly appeared in April 2010 on the NBC TV movie Secrets of the Mountain, two years after ATWT and GL discontinued the logo (PGP continues to produce TV movies to this day), and was also spotted on the 2011 People's Choice Awards.

Final Note
A spin-off company of Procter & Gamble Productions known as "TeleNext Media" was created in 2008 to produce the final episodes of As the World Turns and Guiding Light (GL ended on September 18, 2009, while ATWT followed almost exactly a year later on September 17, 2010). In 2013, the company was renamed "Procter & Gamble Entertainment".
