Context:
In 2000, ABC launched a web-based promotional campaign focused around its circle logo, also called "the dot", in which comic book character Little Dot prompted visitors to "download the dot", a program which would cause the ABC logo to fly around the screen and settle in the bottom-right corner. The network hired the Troika Design Group to design and produce its 2001–02 identity, which continued using the black-and-yellow coloring of the logo and featured dots and stripes in various promotional and identification spots.

Question:
Who was hired to produce ABC's 2001-02 identity?

Troika Design Group
