Excellent point, Cliff, and one I hadn't really considered before. The original laws mandating that television stations build out ATSC facilities had staggered deadlines according to market size and type (profit or non-profit) of station, partly to give smaller stations more time to find the financing, and partly to give equipment manufacturers and tower crews a staggered workload. The original "85% rule" would have almost certainly have had us turning off NTSC market-by-market, not nationwide at once. Hopefully the powers that be will ultimately abandon this silly notion of a single nation-wide cutoff date for NTSC, and instead implement a staggered cutoff timetable. This will allow the CEA to concentrate their supply efforts on a single region at a time, and give everybody a feeling for what the actual impact on the viewing public and television equipment supply chain will be.
