Yes, I would try the namepros marketplace and other areas include: Afernic, sedo, TDNAM (the domain name after market) and other forums. The more places you can get your domain noticed the more chance someone will see it and buy it off you IMHO
I'd take it to the search engine. Look up the keywords + television and take the top ten and write to them. Explain why this would be a great name for their company.
Or list it on an auction like Sedo and let them fight it out.
