how to make youtube channel?

Create a new channel

With a Google Account, you can watch, like, and subscribe. Google Accounts don't come with a YouTube channel by default; without a channel, you have no public presence on YouTube.
To upload, comment, or make playlists, create a public YouTube channel. Currently this can't be done in the Android or iOS YouTube apps, but you can use the mobile site or a computer:

Create a personal channel with your name

1. Make sure you're signed in to YouTube. 
2. Try any action that requires a channel: e.g. upload, post a comment, or create a playlist.
3. If you don't yet have a channel, you'll see a prompt to create a channel.
4. Check the details (with your Google account name and photo) and confirm to create your new channel.

Create a channel with a business or other name

1. On a computer or in a mobile browser, make sure you're signed in to YouTube.
2. Go to All my channels.
3. If you want to make a YouTube channel for a Google+ page that you manage, you can choose it here. Otherwise, choose Create a new channel to set up a channel with a different name than your Google account name.
4. Fill out the details to create your new channel.
