Tomas Villegas was looking for information about a product on YouTube, but couldn't find it. "So I thought, well, I'm sure there's other people looking for it. So I made a video."
Four years later, Villegas, who works at a technical college, has a side business doing product reviews on his YouTube channel. He found that adding a little music really improved his videos.
"It just adds that third dimension that is missing sometimes," he says.
