Implementations and Usage
OMA DRM 1.0 has been implemented in over 550 models of mobile phone. Many mobile operators use OMA DRM for their content services. The first OMA DRM 2.0 implementations were released in early 2005; implementations were installed on mobile phones by the end of 2005. Software implementations for personal computer and PDA clients are also available.
Most of the ringtones pre-installed on mobile phones have implemented DRM. Many commercial ringtone vendors who are not part of any mobile phone carrier do not bother with any form of DRM, perhaps because the number of ringtone vendors is huge, and people will choose to download unprotected ringtones if they can get them. The record industry does not mandate that DRM be implemented on ringtones, unlike most digital music stores. Many ringtones are reverse-engineered by the ringtone provider themselves, so it is their choice whether to implement the DRM.
Since 2006, OMA has been working on DRM 2.0.1 and 2.1, and on new features such as SRM (Secure Removable Media) and SCE (Secure Content Exchange).

Famous quotes containing the word usage:
“Pythagoras, Locke, Socrates—but pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (1788–1824)
