How does the unboxing the gadgets videos work?

I want to know the unboxing gadgets videos' business model and how does it work. Specifically want to know, how do the video makers on youtube channels who do the unboxing of gadgets like iphones, lumia, android phones and tablets etc. 1) Procure the gadget?: Where does the initial money to buy the gadgets come from?; 2) How do they monetize it? I don't see ads on many of their videos; 3) What do they do of the gadgets that they have done with reviewing? Sell them probably?;

Most of them make no money at all for the person posting the video, but if YouTube gets enough extra site traffic as a result then the poster can get a small amount of money.

Most posters buy the gadgets themselves. Many probably sell them a little later to recoup some money to re-spend on their next gadget, but others are simply collectors who are lucky enough to have a high disposable income. Either way, the poster usually loses a bit of money each time, but almost all hobbies cost money.

A very tiny number of posters get so many followers and upload so many videos that they acquire a reputation as gadget blogger. Those people may be actively cultivated by advertisers and publicists to receive loans of new gadgets or sometimes free samples to review.

To summarise: all but a very few spend their own money to produce those videos and do so solely for the pleasure of it and to satisfy their own egos.

  • Why should you always stay up to the date with the latest gadgets? I have a iphone 5 and want my parents to get me a 5s. I told my parents the 5s is faster, better battery, camera and ID scanner (I want that so bad: D) but my parents won't do it! So how can I convince them that you should ALWAYS stay up to date with the latest gadgets?
  • Why is gadgets are so addictive? I had my iphone last year. It is my first time to own a smartphone. It is even fun to have when all my friends had it too. I realized I spent to much of my times on smartphone for social network and whatsapp. I can't control myself. I tried not to online but failed somehow.
  • Why do some people try to show off their expensive gadgets? Like they always keep their iPhone on their hand or wear sunglasses and try to act cool and what not. In reality, they're just losers with no life. So why do people do this? Are they just really insecure?
  • Why do so many people go crazy for new gadgets and technology? Queue up for days just to be the first to get a new iPhone… Upgrading things when the old one works just fine… Why do people want the newest "in" thing so much? What's wrong with buying a phone and keeping it for 5 years until it breaks down and THEN replacing it?
