There is a growing effort by broadcasters to make regular TV content available online. For example, the BBC has developed the BBC iPlayer and the bbc.co.uk website to support replication of most BBC broadcast material. The service has been outstandingly successful: 79.3 million requests were serviced in October 2009. NBC coverage of the 2010 Winter Olympics included live and recently recorded content, complete with commercials.
Whenever there is the possibility of a large or dynamic viewer audience, a reliable CDN is required. CDNs once only used to replicate website content around the world. Now, they have expanded dramatically to handle streaming media. Research and markets estimated the value of CDN services for 2008 at $1.25 billion, up 32 percent from 2007. Top CDNs include Akamai, Mirror Image Internet, Limelight Networks, CDNetworks and Level 3. Streaming media services must deal with content collected from disparate sources and distributed to a growing number of devices.
