Harpo Studios

Background
Harpo Studios (also known as Harpo Productions) is a production company founded by television personality and entrepreneur Oprah Winfrey. Its name is not to be confused with one of the Marx brothers, but it is "Oprah" spelled backwards.

1st Logo (November 4, 1988-2003)
Logo: On a white background, we see a cartoon version of Oprah Winfrey, wearing a jacket over a  dress, pulling a wagon that has "HARPO" (in an ITC Grouch font) with the "O" slanted on it, while on the wagon's outer base, reads "PRODUCTIONS, INC." (set in Akzidenz-Grotesk BQ Medium Extended font). As Oprah stops and lets go of the handle, the wagon continues moving and bumps into her, causing the "HARPO" to shake, then appearing normal. The copyright notice appears on the bottom of the screen, and Oprah curtsies. At the very end, her right hand points to the "O" in "HARPO".

Variants:
 * On late 1988 episodes of The Oprah Winfrey Show, the copyright notice fades in at the end of the logo.
 * The copyright notice, in later years, fades in midway throughout the logo's duration.
 * There is a short version of this logo.
 * Sometimes in 1994, the copyright notice had the text "ALL RIGHTS RESERVED" underneath it.
 * Starting in mid-late 2000, the copyright notice reads "HARPO, INC."
 * Strangely, there is a version with a video freeze at the end for about 7 seconds.
 * On BET prints of the 1988 TV miniseries The Women of Brewster Place, "In Association With" fades in at the same time as the copyright notice. The logo is also filmed and cut-short.
 * On Brewster Place, there is no copyright notice under the logo.

Technique: Cel animation.

Music/Sounds: A somewhat dramatic 10-note synth string/horn fanfare, then 5 more quick notes, a brief piano "pluck", and a final string note. This was composed by Paul David Wilson at Herschel Commercial, who has composed a lot of jingles and scores for TV commercials.

Music/Sounds Variants:
 * The logo had a higher pitch when it was first used in 1988. Starting in Summer 1991, the music is in a normal pitch.
 * On some occasions, the Oprah theme plays over it, or it's silent.
 * On one 1989 Channel 4 airing of a S1 episode of The Oprah Winfrey Show, the last 3 notes of the music repeated when the Midlantic Films logo appeared, most likely due to an editing error. See the first video on the way left for this.

Availability: Ultra rare, despite lasting for 15 years.
 * Seen on The Oprah Winfrey Show episodes from the era. It doesn't appear on reruns on classic Oprah Winfrey Show episodes on OWN, as the network edited out this logo, and replaced it with the 3rd logo.
 * It is also found on the 1988 miniseries The Women of Brewster Place and its spinoff Brewster Place. The other variants are nearly extinct.
 * This was surprisingly spotted on a August 18, 2018 OWN re-airing of a 1999 Oprah Winfrey Show episode, with Aretha Franklin as guest.
 * It has been spotted on a few Oprah episodes seen on Oprah's YouTube channel and it is retained on an episode that was included as a special feature on the 35th Anniversary 4K/Blu Ray release of Ghostbusters I & II.

2nd Logo (November 15, 2005, September 18, 2006-2010)
Logo: On a black background, we see "HARPO PRODUCTIONS, INC." in the same font as the 1st logo, with the "O" slanted, rotating towards us. There is a reflection of the name on the base, and the name shines with "pings". The reflection disappears at the end.

Variants:
 * Sometimes, "INC." doesn't appear next to "PRODUCTIONS".
 * A version exists that starts with the name shining.
 * There is another version where "PRODUCTIONS" is absent.
 * A copyright stamp may appear below.

Technique: CGI.

Music/Sounds: A synth theme with twinkle sounds in the background, or the ending theme of the show.

Availability: The earliest known appearance of this logo is on The Oprah Winfrey Show: 20th Anniversary Collection DVD in 2005 (following the Paramount DVD logo). This later appeared in 2006 on The Rachael Ray Show and Oprah Winfrey's Legends Ball.

3rd Logo (2010-)
Logo: Against a white background, a ring moves up and copies into 5 multicolored rings like a gyroscope, revealing "HARPOSTUDIOS" (set in an Interstate font). During the logo's duration, there is a see-through shadow underneath the rings.

Variants:
 * A copyright stamp may appear below.
 * On some local airings of The Oprah Winfrey Show from 2010-2011, the logo appears on the right side of the screen with the text underneath the rings and the copyright info stacked.
 * Sometimes, the logo reads simply "HARPO". This appeared starting in late 2017 on SuperSoul Sunday.

Technique: CGI created in-house at Harpo Design.

Music/Sounds: A dramatic fanfare which later turns into a flourish at the end (somewhat resemblant of the 1988 logo's music), concluding with a string pluck.

Music/Sounds Variant: Beginning in 2011 on most shows, the first few notes of the fanfare are cut off.

Availability: Common. It's seen on all Oprah Winfrey specials from 2010 to the present time. It is also seen on later episodes of The Oprah Winfrey Show as well as The Rachel Ray Show, The Dr. Oz Show from seasons 2 to 8, SuperSoul Sunday, and the short-lived The Nate Berkus Show. This plasters the 1st logo on OWN reruns of classic The Oprah Winfrey Show episodes.

4th Logo (2019-)
Logo: On a white background, we see the same rings from before, but this time in gold and, much like the Harpo Films logo, rotating as they form. The words "HARPO" and "PRODUCTIONS" then fade in one by one.

Technique: Same as before.

Music/Sounds: None.

Availability: Seen on Oprah's Book Club and Oprah Talks.
