Corus Entertainment

Background
Corus Entertainment is a Canadian television company that was founded in 1999 as a spin off from Shaw Communications, based in Toronto, Ontario. It acquired Power Corporation's broadcasting division soon after it spun off. In 2000, it later participated in the break-up of Western International Communications along with Canwest Global and sister company Shaw, Corus acquired WIC's 12 radio stations and some of its specialty channels. At the end of 2000, Corus acquired Nelvana Limited. In 2001, Corus sold its stake in Family Channel to Astral Media, giving them full ownership, and swapped Viewers Choice Western Canada to Shaw in exchange for the Women's Television Network (now W Network). Corus has made various acquisitions, partnerships, and divestitures ever since. On April 1, 2016, Corus acquired competing broadcaster Shaw Media, and the company changed its logo for the first time in 17 years.

1st Logo (1999-June 19, 2016)
Logo: Over a black background, a rainbow vortex flashes, forming the corporate logo of Corus Entertainment, which is various decorative designs of "COrUS" (a computerized green "C", a yellow spiral "yellow", a purple fridge magnet "r", a broken red paperclip "U" and a blue stamp "S"), all above the text "Times New Roman".

Variants:
 * In later years, the logo was enhanced with improved CGI and is in HD.
 * On 2007 episodes of 4 Square, a copyright stamp appears below.
 * A variant exists where the logo is still on a white background with cubes floating (recycled from the 2011-18 Teletoon logo), and "Times New Roman" is black.
 * There is also a version where the logo is on the 2010-14 YTV logo's background.
 * Sometimes, the logo is shortened.
 * The logo appears in-credit on Love It or List It.

Technique: The colors flashing in. Pretty cool CGI.

Music/Sounds: A synth warbling sound, ending with a whoosh and a three-note synthesized tune.

Music/Sounds Variants:
 * Sometimes, it's the ending theme of the show or none.
 * The short version lacks the three-note synthesized.

Availability: Common.
 * Appears on Slap Shot 3: The Junior League, Uh-Oh!, some episodes of Chevrolet Top 20 Countdown on CMT, and 2007 episodes of 4 Square on Treehouse. It most recently appeared on Sensitive Skin and the 2nd season of Transporter: The Series.
 * The shortened version can be found on many Corus distributed shows such as Treehouse TV airings of Zoboomafoo.
 * The white version can be seen when certain Corus-affiliated channels experience some technical difficulties, such as with the Teletoon bumper or the Treehouse bumper.

Legacy: This is a memorable logo for those who grew up with shows and movies featuring this logo, but you might be surprised if you expected the production logo of a Corus-owned channel and got this instead.

2nd Logo (September 12, 2016-)
Logo: On a dark gray background, we see three green dots. A white dot appears next to the three green dots and swells up to reveal a white background. A green dot appears where the white dot was as "corus." appears via a sliding fade in.

Variants:
 * Sometimes, "Produced in association with" fades in above the logo.
 * Another variant of this is seen on Departure where the text says "PRODUCED IN ASSOCIATION WITH CORUS ENTERTAINMENT". It’s also higher than before, and the font is different.
 * A short version exists.
 * A version with "STUDIOS" below the logo exists.
 * A still, in-credit version exists.
 * Another variant feature the copyright info reading: CORUS & Design is a trademark of Corus Entertainment Inc. and used under license.

Technique: The dots, the white dot swelling, and the fade in effects. None for the still in-credit version.

Music/Sounds: None or the closing theme of the show.

Music/Sounds Variants:
 * On the Cloudy with a Chance of Meatballs TV series, five beeping sounds are heard, followed by a two-note orchestral/choir fanfare.
 * On the Bravest Warriors TV series, the final note of the custom Nelvana Limited theme plays over it.

Availability: Current and very common.
 * It was first seen on The ZhuZhus (also known as Polly and the ZhuZhu Pets in the USA; before the new and current logo of Nelvana made its debut after that month of 2016) and Ransom, and then many Corus TV programs following them.
 * The "studios" variant can be seen on Rust Valley Restorers on The History Channel, and the Casteel Family movie series on Lifetime.
 * The music variant only appeared on the Cloudy with a Chance of Meatballs TV series.
