I am Verified and have been since March last year, right now it has absolutely nothing to do with Google+ followers... it did when I got verified but that has been changed for a year now.
There are currently two ways:
1. Through your network - Don't believe it when they say they "can't"...it's that they WON'T... they can contact their YouTube partner manager and have you verified very easily...all networks can, the question is if they will.
2. Through YouTube support - If you go to the help center and see the "contact us" at the top right... then you can apply via the YouTube administration option and complete the email form, in order to even see the "contact us" option you need 19,000 HOURS (not minutes) of watchtime over the last 90 days (check your analytics and calculate the minutes into hours).
Again, it has nothing to do with Google+ followers and you don't necessarily need 100,000 subscribers and it's literally just a tick... there are no extra perks or features that you get.
I can get verified on YouTube, Google+, Dailymotion and Player.me...but unfortunately not on YTTalk
