You can see it with any re-runs. I know one channel, WGN, that airs Futurama episodes and always has three or four entire scenes missing, plus several more punchlines edited out. I also suspect that hour prime-time shows have recently added another short commercial break in the final five/ten minutes of show.
What's the difference? Cameras can have extremely high resolutions, digital zoom levels, and parabolic microphones. So they can indeed film you right in your face, and record a quiet conversation, remotely. Would you rather see the cameraman walk up to you, or never know he's there?
By the same logic, every humanitarian foundation also has a vested interest in preserving human suffering and disease. Every mechanic, doctor, technician, developer, or whatever profession that is paid to fix things should be intentionally not fixing them to maximize profit, yes?
