Allow me to clarify the definition of a podcast: an electronic broadcast seen or heard on a PORTABLE device.
YouTube videos are not podcasts because they cannot be stored on a portable device. Although, you can view them on a smartphone inside the YouTube app, an internet connection is required. If YouTubes can be saved for offline use, that classifies them as a podcast.
Webinar: any live sharing of monitors, web-cams, or audio.
While a podcast is usually pre-recorded, webinars might contain live broadcasting or share a live transmission through a virtual network. VPN or remote-desktop is essentially a 1-on-1 Webinar. Skype, GoToMeeting, AdobeCONNECT - they all allow for simultaneous transmission of more than one stream.
So... Does a "webcast" encompass pre-recorded media streamed during live web interactivity?
