The word ‘webinar’ is a blend of ‘web’ and ‘seminar’. A webinar is an event held on the internet which is attended exclusively by an online audience. This distinguishes it from a webcast, which also includes the presence of a physical audience. Other terms used as alternatives for webinar are web event, online seminar, webcast, web lecture and virtual event. Source: What is a webinar
