2K Sports

Background
Sega created the Sega Sports brand in 1993 to publish numerous sports and racing games, mainly for its own platforms (Genesis, Game Gear and Saturn, and later the Dreamcast). When Sega decided to partner with ESPN in 2002, the brand was renamed to ESPN Videogames in 2003. Later in 2005, Sega sold Visual Concepts (the primary developer of the brand), Kush Games, the 2K IP and several sport licenses to Take-Two Interactive and the label was renamed to 2K Sports, until 2014, where the brand name is dropped and was released as simply as 2K (The 2K Sports logo was used on the title screen (except for mobile titles) until 2015).

1st Logo (February 23, 2005-)
Logo: It's similar to the 2K Games animated logo, but the tunnel we fly in is filled with circles rather than rectangles. The resulting logo has an assembled "2K" carving, which instantly goes solid. It has the word "SPORTS" below.

Variants:
 * On Nintendo DS games, the logo is still and has no relief effect.
 * On most games by 2KS, the still logo is inverted.

Technique: The tunnel effect and the rotating shield.

Music/Sounds: A loud majestic trumpet tune.

Availability: Common. The glowing still version on black appears on newer NBA titles, for example NBA 2K11.

2nd Logo (September 26, 2005-September 10, 2009)
Logo: The 2K Sports shield blasts the screen, collecting letters around, and then explodes, unleashing the forms of several sportsmen. They run in every direction, leaving the sole 2KS logo slowly zooming at us. Then it fades.

Technique: The tunnel effect and the rotating shield.

Music/Sounds: Sounds of bang and blast, then crowd cheering.

Availability: Seems to be quite rare. It's known to appear at least on NBA 2K6, MLB 2K6 and The Bigs games.
