Windfall Films

Background
Windfall Films is a television production company founded in 1988 by David Dugan, Ian Duncan, and Oliver Moore. They produced many factual programmes and documentaries for various networks in the United Kingdom and the United States. The company would soon be part of the Argonon group in 2014.

1st Logo (1991-1994)
Logo: On a wall background, we see an apple with a portion of it peeled, revealing to be a filmstrip floating upwards. To the left of the apple is the stacked text " A WINDFALL FILMS PRODUCTION ". Additional in-credit notices may be shown underneath.

Variants:
 * The text may read differently with the apple and background intact. For instance, Red Star in Orbit features FilmCentre Canada, the BBC, and WGBH's names.
 * On Q.E.D. documentaries such as "Plastic Fantastic", the logo is superimposed into the end credits with a portion of its background slightly visible.
 * On the Horizon documentary Colonizing Cyberspace, after Red Green & Blue Company's animation finishes, the apple from this logo fades in and both images zoom out together. The bottom text fades in, reading "A Windfall Films/Red Green & Blue Company Production for BBC Television".

FX/SFX: None.

Music/Sounds: The ending theme of the programme.

Availability: Ultra rare; most programmes from this period consist of documentaries that receive little to no home media releases and are no longer shown on television. Seen on episodes of documentary series, such as Q.E.D. "Plastic Fantastic", Horizon "Colonizing Cyberspace", and Equinoxe "The Elements".

2nd Logo (February 12, 1995-January 2, 2009)
Logo: On a black chalkboard background, the following text is shown: A Production by  Windfall Films  for Channel 4 Fairly visible writing lines are seen within each row excluding the copyright notice underneath. To the right section of the screen, an apple with a parachute is seen falling.

Variants:
 * An early version has the falling apple smaller and the text slightly thinner.
 * The apple may be re-positioned to different sections of the screen, notably on the left. This is to accomodate the Channel 4 logo being on the right.
 * A still version exists.
 * Likewise, a variant has the apple falling in the center.
 * Sometimes, additional in-credit information will be added underneath with a different texture but having the same writing lines as the other rows. Otherwise, it is simply text in a normal style.
 * Beginning around 2001, the Channel 4 notice is removed.
 * Early 2000's Channel 4 co-produced programmes has the company name shrunken to make room for said company's logo.
 * On Men of Iron, the company name is slightly squished.
 * On Huge Moves, the company name, alongside in-credit information, is centered with the writing lines removed.
 * An in-credit variant exists, consisting of the text in the same font as the end credits but with the apple included, falling over it.
 * On 2004 episodes of the Royal Institution Christmas Lectures, the "Windfall Films" name is exactly the one used in the on-screen logo.
 * On some programmes produced for Channel 5, the logo is boxed with the apple and parachute underneath and above "Wind" in "Windfall" respectively.
 * An extremely rare variant has the right half be a portion of the on-screen logo. Windfall Film's name is not only shown, but also Channel 5, The British Museum, and The History Channel.
 * On Sas: The Real Story, the logo is squished and the Channel 4 text notice reads "Times New Roman".

FX/SFX: Live-action.

Music/Sounds: None or the ending theme of the programme.

Availability: Uncommon. Seen on many documentaries from both the US and the UK produced for various networks from Channel 4 and Channel 5 to WGBH, Discovery Channel, and The Learning Channel, among others. The logo debuted on Reality on the Rocks and was last seen on the 2008 Royal Institution Christmas Lecture episodes. Speaking of the latter, it appeared on said programme from 2000 to 2008 except for 2001 and 2005, as the latter was produced by Mentorn during the programme's switch to Channel 5. It would also appear on Sas: The Real Story, some Equinoxe documentaries such as Meningitis: Search for a Cure, Men of Iron, among many others. Some of these programmes are preserved on home media such as VCI's VHS release of Escape From Colditz and some DVDs of American co-produced documentaries. This logo does not appear on most NOVA or National Geographic documentaries such as Big, Bigger, Biggest and Commanders at War.
