The .tv domain was give for the country code of Tuvalu as far the almighty Google Wiki's among other say... would www.fostersbeer.tv be bad for SERP's in both Google and Yahoo if you live outside Tuvalu? Another goody I still have skepticism that I am testing but with no results yet... I live in Puerto Rico, choosed .Us as a domain extension, still no results for a keyword with very little competition in none of search engines...perhaps I need more café or better morning juice to see my little morning experiment thrive... Your thoughts
SERP/SEO is independent of the domain extension as far as I have experienced. Its more about the content inside the page.
Domain extension is NOT one of the top 100 factors of SEO...If your sites are new then you are probably in the sandbox, and it doesn't matter which extension you have.
