Back in September, Twitter unveiled a new homepage design which included an enhanced sidebar that allows users now to incorporate YouTube videos, Flickr photos, Ustream, and iTunes's Ping social network, without leaving the news stream.
On Monday Twitter announced several new media partners, including Instagram, Dipdive, Rdio, and SlideShare. In addition, the social network has added Blip.tv to the list. Blip.tv is the next generation television network: http://blip.tv/
It gives Twitter users the ability to integrate more than 50,000 independently produced web TV shows from Blip.tv within their tweets.
