To add to the confusion the latest EICTA specs specify Full-HD sets as HD Ready 1080p (this adds 1920 x 1080 playback of 1080p50/60/24.

Great!
imagine going into a pub and being asked whether you want a pint of beer or a 'full' pint of beer or we can sell you a glass that's ready for a pint of beer, but doesn't actually hold a full pint of beer.
I think my head would explode.
Back in 2005 (when the HD Ready specification was launched) there were no 1080 line displays nor any TV's with built in HD tuning capability. The first HD displays were largely Plasma 720 line displays with only analogue component inputs, later LCD TV's largely had 768 lines apart from those using panels generally intended for PC monitor use. Sky boxes supported these for a number of years by virtue of allowing component HD outputs. Of course these did not support the HDCP requirements of the then experimental anamorphic HD BBC Test HD satellite service (1440 x 1080). This required both the capability to natively support 1080i sources and have HDCP capability via DVI or HDMI connections.
EICTA specified HD Ready to ensure that any new TV's bought would work with the only available broadcast sources at the time and foreseen for the foreseeable future. Blu-ray and 1080P didn't appear on the market until the following year and Freeview-HD using DVB-T2 and satellite services using DVB-S2 didn't exist.
