For most of human history, to be successful, businesses had to build solid personal relationships with customers. From booths at ancient markets to the American general store, businesses have relied on human interaction to build a base of loyal and happy customers.

At general stores like this one, there was always someone behind the counter to chat with.

But these days, many businesses have virtual storefronts. If you're not running a booth at the local agora or a general store at the railroad crossing, how can you create an old-fashioned connection with customers? Posting an online video is one great way to introduce the people behind your product.
