Many of these videos are available on other channels, but I post them on my channel so that I can include English subtitles for the hearing impaired and for the billion or so people who know English as a foreign language but need the subtitles to improve their comprehension. I created these subtitle files as an educational project for my students. If the owners of the material are displeased, I will remove the videos and send them the subtitle files upon request. This channel is non-commercial. It does not obtain advertising revenue.
