I haven’t heard anyone buzz about, recommend, or admit to watching SNL in, oh, a generation. But suddenly, I hear lots of buzz about the show. And it’s not because millions happened to start watching when the show happened to actually be fnny again. No, the buzz is born because folks started distributing a Narnia bit, which indeed is funny, on the internet… and people are linking to it (that’s a Technorati chart to the right)… and NBC was smart enough to distribute it, free, on iTunes.

SNL’s Nielsen ratings on 12/17/05: 6.1/14. Jeff, you can explain these numbers better than I, but suffice to say, SNL is far from dead or unwatched — actually it is massively popular — despite that (maybe because) old fogies like Jeff and I go to sleep well before it airs.
Ain’t no way that video would have been aspopular on the web without the massive exposure it received in (gasp) good ol’ fashioned broadcast TV…
