It’s already mid-June, which means summer in the U.S. and a new set of On The Rise program nominees are here. We’re proud of our talented partners, and we invite you to check out these folks and vote for your favorite in the poll at the top right corner of the blog.Here’s how it works: we identify channels who have grown their subscriber base in the past 30 days but haven’t yet reached 100,000. You vote on your favorite on the poll, and at the end of the week, the nominee with the most votes wins exposure on the YouTube homepage and videos page, as well as posts on Facebook and Twitter . Past winners like joshsundquist theslowmoguys , and cutegirlshairstyles have seen their channels grow, all thanks to your support.This month’s nominees showcase a range of video that will teach you, entertain you and thrill you. Take a look at their featured videos below, and cast your vote by June 22 at 6:00pm PT. Please note that only votes in the poll on the blog will count, and we’ll announce the channel with the most votes on this blog and the YouTube homepage on June 29.
