Henry Blodget in the Silicon Valley Insider looks at CNBC’s new website (and manages to work in a shot at Jim Cramer, natch)…

What is really killing CNBC online is the inability to stream every show live. Most executives (though not all) don’t want or aren’t allowed to have flat-screen TVs hanging in their offices, and the ones on Wall Street trading floors are just eye-candy. If CNBC were streamed online, however, just about every Wall Street executive would sneak an occasional peak, and some would keep a window permanently open on their screens.

What is preventing this obvious killer app? Most likely fear of cannibalization, combined with the network’s agreements with cable companies. The cannibalization concern could be neutralized if CNBC charged, say, $5 a month for more than, say, 5 minutes a week: Those who could rationalize this modest subscription as a “work-related expense” would pay it. So it’s probably the cable companies.
