THIS seems like a moment of some significance:

LOS ANGELES (Reuters) – The Fox News cable channel made a bit of television history by drawing more viewers than any of the Big Three broadcast networks on the opening night of major coverage of the Republican convention, according to figures issued on Wednesday.

Fox News’ presentation of Tuesday’s speeches by California Gov. Arnold Schwarzenegger and first lady Laura Bush drew 5.4 million viewers, more than broadcasters ABC, CBS or NBC.

That marked what is believed to be the first time a cable channel has grabbed the biggest audience for a telecast of a single event covered by all the networks, Fox said.

I’m not sure exactly what it means, except that the old media folks have no business being complacent.
