Multimedia Messaging Service, or MMS, is a standard way to send messages that include multimedia content to and from mobile phones. It extends the core SMS (Short Message Service) capability which only allowed exchange of text messages up to 160 characters in length.
The most popular use is to send photographs from camera-equipped handsets, although it is also popular as a method of delivering news and entertainment content including videos, pictures, text pages and ringtones.
The standard is developed by the Open Mobile Alliance (OMA), although during development it was part of the 3GPP and WAPgroups.
