One might say that HDTV is 720P and 1080i , and then Full HDTV is 1080P. <><> And then one might get in to , i = interlaced scanning , and P = progressive scanning. And then one might know that i- interlaced scan lines do not quite match up and what this does is , have you ever noticed that stripes in the picture striped ties and striped shirts have a rainbow effect , and if the tv camera is moved up and down or down and up , the picture has a wavy effect , that's i-interlaced scanning. <><> Progressive scanning will have little or none of this. <><> So any way , one might call it a marketing thing. <><> Humans like the WOW! factor. Like --> WOW!!!!! it's FULL HDTV , the eyes light up , the nostrils flare open , the chest puffs out , and then the person relaxes with a satisfied feeling. <><> So here is the truth as I see it , The Digital Pictures of 480i and 480P <--low definition and 720P , 1080i , 1080P <--high definition are nice clear pictures , no ghost , no bad colors , no drifting lines , no snow that analog tv has. <><> Digital TV has a nice clear picture picture and I like that.
The original answer is correct in that it is mostly marketing but it has come to symbolize the difference between 720p/1080i vs. 1080p. Many Blu-ray discs, PS3 and Xbox360 games as well as Televisions will boast Full HD. It simply means it has the capability of outputting 1080p.
HDTV = High Definition Television
you need a HDMI cable and 1080P media like a Blue ray disc and a HDTV with 10080P capabilities before you will receive full 1080P. For example most HD TV programing is only 720P and will not be in full 1080P on a 1080P HDTV and a TV show in 480i standard will be in 480i on a 1080P HDTV

Yes, LG does make a 40 inch HDTV, as well as many others. Take a look at http://www.lg.com, in order to get a full idea of the kind of selection that LG has.
An HDTV should not eventually stop scanning for channels. Provided you have properly cared for your TV, this is not a common problem.
You can look at your HDTV as being more important in the decision over Xbox 360 and PS3 because there signals go to the HDTV which for most people including myself is not even an LED HDTV
the ease of filtering their outpot voltages
