Webcast, live stream, Webinar, podcast, Vodcast, …
There are many expressions for real-time transmissions or recordings on the Internet.
It is easy to explain the difference between a podcast and a vodcast, the first one is only audio-related content and the other is for video. It is not that easy to find the difference between a webcast and a live stream. A lot of people out there want to make a webcast and a live stream – but here is the think: There is no difference! The word “webcast” (“web” and “cast”) stands for “World Wide Web” and “Broadcast”, and has the same meaning as live stream. Live stream is just the newer word for real-time transmissions on the Internet. It also doesn’t matter if the Broadcaster transmits his event via Smartphone to Periscope or Meerkat, or if a TV-Channel is streaming all cameras on different streams and the viewer can choose his favorite angle. The most successful live stream or webcast ever, was Felix Baumgartner’s supersonic freefall in 2012.
After flying to an altitude of 39,045 meters (128,100 feet) in a helium-filled balloon, Felix Baumgartner completed a record breaking jump from the edge of space, exactly 65 years after Chuck Yeager first broke the sound barrier flying in an experimental rocket-powered airplane. Felix reached a maximum of speed of 1,357.6 km/h or 843.6 mph(Mach 1.25) through the near vacuum of the stratosphere before being slowed by the atmosphere later during his 4:20 minute long freefall. The 43-year-old Austrian skydiving expert also broke two other world records (highest freefall, highest manned balloon flight), leaving the one for the longest freefall to project mentor Col. Joe Kittinger
