Assuming there are no trademark issues, it is a potentially useful name for a tv service, especially one that is not commercial. It is nice that it is so short. On Namebio the only 1tv sale that shows is for the .ch extension, a very nice $4800 sale. However, at GoValue it also shows $100 sales in both the .org and the .net extensions (they don't say when those were). I see that 7tv(.)net sold for $121 back in 2013 (and 9tv in com in 2015). I could see this going for anywhere from low $$$ to lowish $$$$. The number of potential purchasers is somewhat limited. Good luck with it.
