Poker software CD is popularly sold as two types.  The read only CDs are that which one will not be able to be copy to the directory to make multiple copies and distribute it for their friends to play. The next one are the poker software CD that can be easily copied and can be replicated in to 100 and more copies with the help of a CD writer and can be passed on to their friends for playing.

The poker software CD that cannot be copied is copy protected by several methods.  Developers use a special program to write the software and it will not be readable or interpretable by any program other than which was used to create it.  This kind of copy protection is done for poker software CD that has really useful material that took out hours and hours of work of a team of programming professionals and it would also have swallowed a major investment. It is quite natural for the investor or the creator of such a valuable product to expect some profit from selling the poker software CD.

If the company that is selling the poker software CD is not taking enough caution to make it copy protected, chances are very likely that the competitors are going to spend a very small sum to purchase the CD and they will just make replicas and even give it away for free, thus making it difficult for the initial investor to make any money out of the sales.

An expert marketing person would be sure of all such marketing problems and to make the copy-protection more viable they retain the copy of the programming language with script keys with them.  Script keys are those parts of the program that tells the function of a particular code in the program.  They just release the poker software CD without the script keys that details the functioning of the code.  When such a CD is released it will become more difficult for the third party to decipher the functioning of each code without script keys; however, there are pirates that decode all complications and make a duplicate product, but an efficient marketing plan would make a better sale before the duplicate product can reach the market.

Poker software CD that are given out as which can be copied are those that are really meant to make the CD available to as many people as possible.  By doing so, the company gets automatically advertised among many poker fans!
