Better than YouTube

YouTube is for videos and podcast is audio only. You can’t play really a YouTube video on your mobile phone with the screen off nor have the same controls in the lockscreen as you have for podcasts. 

Most of the documentary or educational style videos are better to be listened to audio only; because it is vey hard to put visual material for the full length of the video that supplements the audio. Most of the time the video becomes a distraction and gets in the way of the message being delivered.
