Dwight Merriman and Kevin Ryan are co-founders of DoubleClick, the giant ad serving technology platform sold to a private equity firm in 2005 for $1.1 billion and later to Google.

The two have been building new businesses including a content delivery network (CDN) called Panther Express.   Earlier this year, Kevin told  Beet.TV that Panther is the industry’s third largest CDN.

I caught up with Dwight last week at the Contentinople conference in New York.  He explained that his company provides only progressive downloads, not streaming.  Evidently, with big customers like Gawker Media, this scenario is working quite well.

Dwight spoke about emerging technology emerging from New York’s Silicon Alley, where Panther is based.  Dwight and Kevin also own the Silicon Alley Insider, one of favorite blogs here at the purple network.
