I’d argue it doesn’t accurately show the relative value at a cursory glance. The chart shows the area under the curve having decreased over 90%, but when looking at the y-axis, you can see that initial assessment was misled.
In a speculative industry like finance, shouldn’t we try our best to make charts less… alarmist?
Ditto. We went from having five channels, one snowy on a bad day, plus a bonus 6th channel when the stars aligned, to two channels at best.
The broadcasters and regulators took a basic fact about digital signals “We can get a better quality signal with less transmission power” and saw it as a challenge to set up their digital transmitters with the most conservative estimate of minimum power required. I haven’t studied well enough for my amateur radio exam to know if I’m comparing apples to oranges, but I’m still shocked to see descriptions of transmitter power go from 100kW in one case to below 20kW.
