Digital is cheaper for two possible reasons. The answer will be determined by your question of type of digital as in physical components or radio based transmissions.
Number one:
Digital devices can be made smaller with less components than analog.
Number two:
More information can be transmitted over the same available transmission space using digital than can be with analog.
