Hi everybody,
Youtube is a combination of an (1) old idea, plus a (2) new technology.
(1)
The old idea about youtube is to exchange Videos (for fun, business purpose, or misc.), Music (many users simple post just one picture with a whole song) and thoughts.
These concepts are no innovations: People did share music (napster), videos (via an FTP or kazaa, or else) and thoughts (chatrooms, etc.) via Internet before Youtube.
(2)
The internet improved a lot the last years. The latest "wave" was called "web 2.0" which overall means that now everybody is enabled to do blogs, to "twitter", upload files or videos just by doing some little klicks and ...comment on nearly everything. Before the days of "web 2.0" these abilities where up to webmasters or people that are really used to the internet. For example my father: Did he knew how to get his videos from Camera on his website? (he had now clue about compression rates^^) No he didn't.
So, in the end I have to say: No, Youtube is not an innavotion itself, because the idea AND the technology was not invented by the creators. But, it is the best working combination of those two and has a large number of users.
What is Youtube?
Youtube itself: A web 2.0 based Community-Video-Blog
For the creators/owners: A video blog to raise a large number of users to gain money through advertisements and Premium users.
For the people, us: everything we intend it to be, e.g. entertainment, news channel, free tv/music plattform, business communication, ...
Kind regards,
Oliver
