Webinars can be used to engage and teach a large audience spread across different physical locations about any subject, product, or cause. This removes the need for the presenter and the audience to travel, or to set up a physical venue for delivering a presentation. Webinars are becoming increasingly popular in the fields of education, business, and consulting and have already evolved as an effective, low-cost marketing tool. Many businesses conduct webinars regularly to educate customers, attract leads, and promote their brands.
