I'm even more mad that sound quality in radio interviews actually decreased. People used to use landlines for calling, given that very recognizable sound "quality" (which is of course nowhere close to what ISDN could do). Now as (almost) everybody uses cell phones, quality is sometimes good, sometimes very poor depending on network conditions. It's not rare to hear the consequences of dropped packets. Sometimes it also sounds bad with apparently no drops, not sure why: maybe are people using the phone in "hands-free" mode so they don't need to keep it in their hands?
