from a YouTube press release
To help people share their talent, imaginations and experiences with the world, YouTube users can now become their own Channels. Rather than following the traditional TV model where executives and companies are telling viewers what to watch, YouTube is now empowering its community to take control and be masters of their own entertainment domain.
Video content creators, be it user generated or professional content, are becoming the online broadcasters, record labels and movie studios of tomorrow. Channels give them the ability to control and share entertainment a privilege long enjoyed only by traditional media. People can decide what is entertaining for them and what their audience wants from skydiving to political content and put it on their Channel for all to see.
Channels can be customized too. Filmmakers, comedians and musicians among others, are looking for ways to showcase their personalities and brands though their Channel. Each Channel is its own brand and YouTube wants to help people promote their creativity and original content.

YouTube now has a Video Response feature that allows users to communicate with each other through video and upload their own video reply rather than using a static text comment. There is a post a video response link on the video watch page. All video responses will show up directly beneath the original video (just like text comments).
We recently noticed that within many of the different ecosystems on YouTube our users are doing something really cool – they’re communicating with each other through their videos. Text comments and messages are great, but our users have once again created something really innovative completely on their own – video responses. It’s been amazing to watch our users create an entirely new mechanism for communicating with one another.
