Booming business services?When I tote up the MSO numbers each quarter, it just amazes how cable business services revenues continue to grow. The growth curves are simply not flattening out, except for maybe Cablevision's Lightpath unit, even as the base amounts keep increasing. If all goes according to this pattern, the US MSOs could hit $10 bilion in combined revenues next year. So I wonder what the upper limit will be. $12 billion? $15 billion? $20 billion or more? I just don't know.
