Full contact between this sport name and the .tv extension. No doubt a real good investment. I agree with Damion the name alone is worth $10,000. It has the advantage to cover all forms of kickboxing such as Japanese, Indian, Khmer, Thai, Chinese, Burmese, and others such as the American kickboxing (full contact karate) and the French one (Savate), I may forget some but would add popular variants such as aerobic and cardio kickboxing (my wife

). Meaning that, as you know, this sport has more than 50 millions subscribers worldwide (hundreds of millions of martial arts fans) kickboxing has its own fighting stars, a GROWING success (particularly boosted by the very popular 3D kickboxing games we all know), there is a recent but real industry behing and Kickboxing is getting more and more visibility on screen and could in a near future compete with major boxing and wrestling tv show$. I do not know whether you have time, a full time job, and money to develop the name as it would deserve, I would at least develop the concept/project on paper and promote/test it in getting in touch first with the right persons at EuroSport, ESPN,... and discuss possible support from major obvious kickboxing sponsors such as Coca Cola, Budweiser, Everlast, Montana, SDI,...., even Sony, Pinnacle Sports... You have THE name and the appropriate extension, test and spread the idea.
