youtube's failure to generate substantial income

The register has a story on an analyst's estimate (whatever that's worth these days) that youtube will be losing close to half a billion $ this year. They take this as an indication that the ad model is not working. After discussing two reasons why this might be the case -- either Google doesn't know how to do it (unlikely) or the model is fundamentally broken (more likely) -- they come up with an option for Google to make money out of youtube.
