I'm posting this, not because of the every grow survelience society which we live in, but more about the improvements in technology with a thought of what could happen in the TV sector in terms of picture quality:

BBC News - High-def CCTV cameras risk backlash, warns UK watchdog
High-definition closed-circuit television (CCTV) risks sparking a public backlash, according to the UK government's surveillance commissioner.

Andrew Rennison told the Independent newspaper that "the technology has overtaken our ability to regulate it".

Surveillance cams now offer up to 29 megapixels, surpassing many cameras used by professional photographers.

Manufacturer's figures suggest there will be 129,299 HD CCTV cameras in the UK by the end of 2012.

The HDCCTV Alliance has predicted that number would rise to over 3.7 million by 2016.

A shift from the use of analogue to digital equipment is also helping drive the quality of the images the cameras capture...

...It added that the adoption of internet-connected cameras meant that more footage was being stored off-site for longer periods of time, and that gigapixel camera technology would mean even higher quality images in the future.
