A computer lesson video

I choose this video because the song of the video is the main song of an online-game which called "Tales runner".I like playing it very much.It is exicting and amazing.I also like the asinger Stephy's sweet voice,the lyrics and melody of the song.

Broadcast
meaning:to spread something around to let others know.
I choose this word because I think Youtube is a way that we upload the videos to show ourselves to others.
