Crowdsourcing is: Use the crowd as wisdom
Often the internet is used for this, but it can also be done via a telephone survey. As a company you have an idea/product but want to improve it. To do this, turn the audience on, and leave those comments, make points of improvement, etc. A company can present a problem to a large group of people and do relatively cheap research (no expensive R&D department needed). In addition, you often get comments from different groups of people, which is also a kind of market research. A modern and small-scale way to Crowdsourcen is to ask your question via Twitter.
