Is Shockwave content recognized by all web browsers?

Over 95% of all web browsers do recognize Shockwave content. For those clients which do not, the Shockwave player will need to be installed. For those who do not download and install the player, Shockwave content will be unrecognized.

This is a downfall to Shockwave - it is not supported by all web browsers.
