Origin

Origin (formerly known as EA Download Manager or EADM) is the digital distribution service developed by EA. Origin is used to download and install digital versions of purchased games as well as their updates. Origin is the chief competitor to Valve's Steam content distribution service. Origin has been a mandatory requirement for all EA titles released since 2011.

History
The service was initially launched as EA Downloader in 2005 and was used to distribute Battlefield 2 expansion packs. The service was re-branded as EA Download Manager in 2007 and purchases from the EA Store were downloaded via the EADM client.

The EA Store and EADM client were merged and re-branded as Origin in June 2011.
