An enlightening essay by Paul Saffo on what analog TV “snow” is — and why he’s keeping his old TV around:

“This is why I won’t throw out my analog TV or retire its rabbit ears any time soon. Analog broadcast has gone mute, but the longest-running TV show in the universe - the cosmic radiation of the Big Bang— is still playing and I might want to tune in from time to time. Maybe it will help me get to sleep some night, and who knows, perhaps the Universe will whisper a secret in my ear.”
