Uses
"The BNC connector is used for professional video connections, both for analog and Serial Digital Interface signals, amateur radio antenna connections, aviation electronics (avionics) and on nearly every piece of electronic test equipment manufactured in the last 35 or so years."
This reads as if it was started referring only to video uses then other uses have been added.  Perhaps a more general summary of uses of the BNC would be better.  Also the statement about electronic test equipment is not correct.  N connectors are more common on much RF test equipment.
