The largest independent content sites
Quantcast makes it easy to see the largest one million sites in the US (by traffic). There's a signficant consolidation going on, with the vast majority of popular sites being owned and controlled by larger, public companies.
Because onine traffic follows, as most things do, a power law curve, the top 100 sites account for a huge amount of overall web traffic–probably more than the next 900 sites combined.
After removing public companies and those that only do commerce, here are the thirty independent companies on the top 100:
