Twitter on Monday announced several new media partners that will allow their products to be viewable via the "new Twitter" preview panes, including blip.tv and Rdio.

In September, Twitter unveiled a new homepage design that included an enhanced sidebar that allowed users to display images, video, and user profile information without leaving the news stream. This "new Twitter" was fully rolled out to all users by mid-October, and included partners like YouTube, Flickr, Ustream, and iTunes's Ping social network.

Twitter is now extending this feature to blip.tv, Instagram, Rdio, SlideShare, and Dipdive.

With blip.tv, Twitter users can watch more than 50,000 independently produced Web TV shows, Twitter said in a blog post.

Instagram, meanwhile, debuted as iPhone app in October, and lets users add 11 different custom filters to photos in order to change the colors, mood, border, and tonality of their snapshots. Now, users can look at these photos right in the Twitter stream. DipDive will also let users share photos, videos, and other works from the company's community of artists.

Rdio is another relatively new service. It was launched in August by Skype and Kazaa co-founders Janus Friis with Niklas Zennström. Now, "when a subscriber Tweets out a song, Rdio members can listen to full-length songs right inside the details pane, for the first time ever," Twitter said. "All other Twitter users will hear 30 second song previews."

Need to get some work done? SlideShare will let you share and read entire presentations, directly on Twitter. "We've always made speed an important focus for the SlideShare experience and enabled embedding broadly across the Web," SlideShare said in a blog post. "This should enhance the experience on #newtwitter and increase the number of views for content shared on SlideShare as it goes viral on Twitter."
