Mostly videos of phones and other electronic items I find interesting.
Most of the phones I get are from my business. I started an electronics recycling firm if you will, where I'll buy out devices when corporations such as insurance companies, etc, all upgrade their "fleets" and then either part them out for parts/repair or resell them if there is value to them. I started this after I used to "collect" I say this loosely because I always liked electronics and phones, and upgraded to the newest models whenever they came out. What happened, was that a LOT of electronics got built up around me, and I ended up basically starting to make videos about them, and how electronics interested me. Then later on came the whole business thing. I've always liked watching electronics videos, and someone came to me with the idea that I should make a ringtones video of a particular phone, then came the channel.
