Video and Audio sites

Before you begin here, you should also know that there are quite a few OVPs (online video providers) like YouTube, Dailymotion, and Vimeo, and online audio providers like Soundcloud.

Such companies offer a convenient, easy way to host and consume videos, so you don't have to worry about the enormous bandwidth consumption.

OVPs even usually offer ready-made code for embedding video/audio in your webpages; if you use that route, you can avoid some of the difficulties we discuss in this article. We'll be discussing this kind of service a bit more in the next article.
