No, you said it is "doomed". If your definition of doomed means that they are not going to be the #1 video sharing site on the internet, that's a pretty interesting definition of doomed. That definition would make the following companies "doomed":
- Yahoo - Facebook - BP - Unilever - Anyone else who isn't #1 in their space
Usually when people say "doomed", they imply that something fails. A usual definition of "failure" with regards to companies is something that is unprofitable and fails to gain traction. I doubt that either of those will apply to this new venture launched by News Corp and GE - the parent companies of Fox and NBC.
Big companies make plenty of mistakes, but when this much is at stake and $100 MM is being invested by a third-party, they're going to make something happen. I'm willing to bet you that their venture will be within the Top 5 video sharing sites within 2 years of launch and will not shut down within 2 years of launch.
