Does anything broadcast in 120hz or higher?

The standard display rates are 60Hz for North America and 50Hz for Europe. No broadcast material is delivered at 120Hz nor at 100Hz in Europe. There are no plans to move to higher frame rates.

120Hz (100Hz in Europe) is offered as a "flicker free" technology in some high end televisions. The television takes the incoming signal and adds intermediate frames to double the number of frames each second.

Whether or not the process offers a better picture is a matter of opinion. Some say that it actually reduces image quality and others will say it improves it. Adding frames will not actually add more information to the image because no interpolation system can add detail that has not been captured by the original cameras. If the view prefers a frame doubled image, that is good enough reason to use it.
