That if I tune the TV set to a none broadcasting channel, The static I see is remnants of the Big Bang?

only a small part of the static is from the big bang. in addition to tuned to an unused channel, you should also turn the brightness all the way down.
timothy ferris states in his pbs show "the creation of the universe" the about one percent of the remaining static comes from the cosmic microwave background.

It is 100% true that some of the static is from the Big Bang. It's called Cosmic Microwave Background Radiation or something like that. The rest of the static is from all of the electrical stuff on Earth.

Yes, it's true that a small fraction (not more than 25%) of the noise that you see on the screen is cosmic background microwave radiation left over from the Big Bang.
In 1965, two Electrical Engineers (Penzias and Wilson) won the Nobel Prize for showing that microwave radiation was being emitted uniformly from all parts of the sky. This was later labeled the "cosmic microwave background radiation" or "CMBR" or simply "CBR."
The radiation from the Big Bang (high energy photons present just after the Big Bang) has cooled over time (for a number of reasons, some involving the expansion of the universe) and have downshifted in frequency. Now they sit in the microwave spectrum and are thus picked up by RF antennas, like the one in your television. Even though this radiation has downshifted in frequency, it still contains information about what the universe "looked like." Imagine a photograph changing color. Even though the colors change, the image still retains most of its important qualities. Scientists use the CBR to tell them interesting things about the topology of the universe and characteristics that must have been true just after the Big Bang.

By definition, everything that you see is a remnant of the Big Bang.

Hi. Probably some of it, but there is a lot of static from weather, car ignitions, etc.

Yes. The link at CERN (below) discusses this credibly.

No actually it is the reminents of all the shows that were not picked up by networks.
