Blizzard Entertainment

Background
Blizzard Entertainment (formerly "Silicon & Synapse") was founded on February 8, 1991 by Michael Morhaime, Allen Adham, and Frank Pearce. It had to be renamed to its current name in 1994 shortly after being sued by Interplay Entertainment. In July 2008, it merged with Activision to become Activision Blizzard, but it still remains a subsidiary of it. They are best known for creating the Warcraft, Diablo, and StarCraft franchises, all of which have become worldwide hits.

1st Logo (August 1994-October 27, 1995)
Logo: On a black background, we see the text "BLIZZARD ENTERTAINMENT", with "BLIZZARD" in a jagged font, and "ENTERTAINMENT" in a straight font.

Variants:
 * On the Sega 32X version of BlackThrone, the logo is in CGI and has a spotlight-like effect. Plus, "ENTERTAINMENT" is in a different font and it's a bit bigger than before.
 * On the SNES version of The Lost Vikings II, the main characters of the game, Erik, Baleog and Olaf, fall onto the logo and become dizzy.

FX/SFX: None. The animation on The Lost Vikings II variant.

Music/Sounds: A long, quiet "whoosh". Sometimes, the opening theme of the game is heard.

2nd Logo (December 9, 1995-May 8. 1998)
Logo: On a black background, we see the word "BLIZZARD", in the same jagged font as the last logo, fly in from the bottom-left side of the screen. It stops in the center, and a white spark zooms across the screen from left to right, forming the word "ENTERTAINMENT".

FX/SFX: Good CGI for its time.

Music/Sounds: A big, loud "whoosh", followed by a "boom"-like sound that trails off, and some "twinkling".

Availability: Easier to find than the last logo, but still pretty rare. Can be found on Warcraft II and Diablo. It appears on the PlayStation versions of said titles as well.

3rd Logo (StarCraft variant) (March 31, 1998-May 25, 2001)
Logo: On a black background, we see a bunch of wavy lines moving around in the middle of the screen. After a few seconds, "BLIZZARD" appears, the wavy lines disappear, and "ENTERTAINMENT" fades in below.

Variant: On the Nintendo 64 version of StarCraft (known as StarCraft 64), it's a still logo.

FX/SFX: The wavy lines, done in really cool effects. None for the still variant.

Availability: Rare. Seen only on StarCraft for Windows, Mac OS, and Nintendo 64.

4th Logo (June 28, 2000-July 5, 2002)
Logo: On a black background, we see multiple lights emitting though the background, much like the 1997 Activision logo. After a few seconds, the lights slowly come together, revealing a black Blizzard logo. "ENTERTAINMENT" shines below the Blizzard logo, and the screen flashes, causing the Blizzard logo to turn, and the lights to disappear.

FX/SFX: Nice animation, which still holds up today.

Music/Sounds: Cracking sounds when the lights are emitting and coming together, a "whoosh" when "ENTERTAINMENT" appears, a "slam", and quiet "twinkling".

7th Logo (World of Warcraft variant) (November 23, 2004-February 11, 2005)
Logo: On a smokey background, the text "TEN YEARS", with a / light shining over it from right to left, fades in. After about four seconds, the text fades out, and more text reading "OF WARCRAFT", with a registered trademark next to "WARCRAFT" and another / light shining over the text from right to left, fades in. After about seven seconds, it fades out, and yet another / light appears, once again shining from right to left, slowly revealing the Blizzard logo, this time in instead of. Once the logo is fully revealed, the light disappears, and the Blizzard logo slowly fades out.

FX/SFX: Impressive animation, clocking the logo in at about 25 seconds.

Availability: Seen on the famous MMORPG World of Warcraft.

8th Logo (January 16, 2007-)
Logo: On a black background, the Blizzard logo from before slowly fades in from the left. When it completely fades in, it flashes, and then slowly fades out.

Variants:
 * Later versions of this logo has the logo shinier and the flashing omitted.

9th Logo (June 2007)
Logo: An extended remake of the 3rd logo: We start out with some static. The static disappears, and we see a big explosion of light. The light suddenly zooms to the center of the screen and starts forming the Blizzard logo. Once the logo is completely formed, the light disappears, and "ENTERTAINMENT" fades in below. After a few seconds, more static appears and disappears very quickly, much like a TV being turned off.

10th Logo (June 2008)
Logo: On a black background, we see cracks appearing on various parts of the screen and coming together. As the camera rotates and zooms out, the cracks are revealed to be forming the Blizzard logo. Once the Blizzard logo is completely formed, the cracks disappear, the logo turns, and "ENTERTAINMENT" appears below.

FX/SFX: Once again, very good animation.

Music/Sounds: Cracking sounds when the cracks are forming, and "whooshing" when the cracks disappear.
