What is GRC?/
GRC is a revolutionary new form of motorsport. Some call it a cross between rally and supercross. It features wheel to wheel racing with up to 10 cars competing at once in fast paced heat races over huge jumps on combination dirt and asphalt courses around the world. Watch world champions, crossover legends and others battle it out to be the global champion.
These shows appear to be the same as GRC-TV, a YouTube channel.
I'll be happy to be proven wrong, but if the plentiful sponsorship logos plastered in neon colors are any indication, the corporation who purchased this block of time from NBC is trying to appeal to the under 30 year old, semi-upscale international male users of energy drinks who are fans of small, loud cars driven in circles and jumping off ramps.
