51. Gawker

While some "digital companies" pecked away at the dream in Mom's basement, the Gawker media company went forth and established one of the most powerful networks on the Internets. Steadily killing it in all categories: NY Gossip (Gawker), Sports (Deadspin), video games (Kotaku), auto (Jaloponik) tech (Gizmodo), and porn culture (Fleshbot) it's impossible not to respect the conglomerate.

The Gawker Media Company currently has 7 sites listed in the top 20 on Sitemeter.com.
