We've talked about book trailers before... These are like movie trailers - but they are for books!
It turns out, this has become "mainstream"... A book trailer (usually placed on YouTube) is the latest way to market books!
Here's a recent article about the new phenomenon of book trailers...

Of course, this leads to an opportunity, too... Many authors will need someone to help them make (and upload) their book trailers. If you're good at shooting video and at uploading it to YouTube, there could be a demand for your services from authors...
Best wishes,
