Etymology
The term 'wall-to-wall' originated in the mid-20th century from the interior design and flooring industry. It literally described carpeting that was installed to cover the entire floor space from one wall to the opposite wall, eliminating bare perimeter floors. This concrete, spatial sense of complete coverage was then metaphorically extended to describe anything that is continuous, omnipresent, or exhaustive in its scope, such as media coverage or scheduled events. The logic evolves from a physical measurement of totality to an abstract concept of saturation and non-stop availability.
Analysis
This is a compound adjective formed from the noun 'wall' (from Old English 'weall', meaning a rampart or structure) and the preposition 'to', repeated. It functions as a fixed idiomatic unit.
