On a PC, it may be possible to run Shockwave under Ubuntu using Wine and running the Windows versions of Firefox and the Shockwave player. Unfortunately, the Shockwave player is only available for Windows. Today, Shockwave is most commonly used for Internet games. Designed by Macromedia in the mid 1990s, it was followed by Shockwave Flash (or just Flash), a simpler format which became far more popular.
