1998–2001

In 1998, the mountain-in-a-circle was dropped and the text changed. The company was split into five sub-brands; those being Sierra Studios, Sierra Attractions, Sierra Home, Sierra Sports and Sierra FX.

In 2001, all of the sub-brands were reformed into one universal brand (except Sierra Home, which remained separate) under the Sierra name. Only a few games used this short-lived logo, such as The Operative: No One Lives Forever - Game of the Year Edition.

Sierra Entertainment

2002–2008

After Sierra On-Line changed their name to Sierra Entertainment, they reintroduced the mountain-in-circle logo. In 2008, after Activision merged with Sierra's parent company Vivendi Games to form Activision Blizzard, the brand was absorbed into Activision itself, while selling two of its studios, video game rights, and games that were originally in development for the publisher to other companies.
