As online technology advanced, web sites, podcasts, and blogs became powerful sources of information that allowed everyone to stay updated on any subject imaginable. Although all of these information sources remain popular, there's a new king of media and it's online video.

There are many reasons why online video has increased suddenly over the past few years. The first is increasing data speeds. It wasn't until recently that people everywhere had fast enough online connections to enjoy high-definition （高清）videos. However, once faster Internet speeds were provided, people quickly fell in love with online videos. The second reason why online videos have become so popular is convenience. Watching videos requires less effort and energy than reading through paragraphs of text after a day of hard work. Videos also seem to provide more satisfaction, as people prefer to connect with people they can hear and see, as against the words of some author whom they know little about.

Advancing digital technology has also helped, as it has made sharing videos easier and more convenient than ever. High-powered smartphones and more affordable video cameras allow anyone to easily record an event or give a few comments about a scorching topic that is on their mind. Meanwhile, sites like YouTube, Vimeo, and Ustream allow users to quickly upload their videos and share them with friends, family, and the general public if they wish.

Last but not least, advertising. Companies have made it easy for people to get rewarded for creating popular videos. Some people with large enough fan bases can even make a very wealthy living by uploading a few videos every week.

The future also looks bright for companies who post online video ads. In fact, new software allows them to watch viewers' emotional reactions to their content through the users' webcams （网络摄像机）.They'll be able to see whether users laugh, cry, or feel bored during videos, so they can adjust their ads. This should prove extremely helpful, as there will be millions of videos competing for viewers' attention.
