Way back in 2012 Matt Cutts said:
“I read a post by someone offering new top-level domain (TLDs). They made this claim: ‘Will a new TLD web address automatically be favoured by Google over a .com equivalent? Quite simply, yes it will.’
“Sorry, but that's just not true, and as an engineer in the search quality team at Google, I feel the need to debunk this misconception. Google has a lot of experience in returning relevant web pages, regardless of the top-level domain (TLD). Google will attempt to rank new TLDs appropriately, but I don't expect a new TLD to get any kind of initial preference over .com, and I wouldn't bet on that happening in the long-term either. If you want to register an entirely new TLD for other reasons, that's your choice, but you shouldn't register a TLD in the mistaken belief that you'll get some sort of boost in search engine rankings.”
and I have not seen anything to indicate that this is no longer true.
Some people like to get the new tlds because they feel that they will be attractive to the user, that if for instance people see a .tv they would choose it over another page because they would think that a .tv provides a better video experience.
This may be true, but on the other hand, there are plenty of people who no longer think of tv when they think of the video experience...
