We’ve been remiss the past few weeks in highlighting some of the great new Tumblr blogs from major media companies. No longer! A look at some of the good media projects that have launched on Tumblr in the past few months.

• The LA Times returns with a sharp, engaging Tumblr blog that broadens the mandate of the paper’s longtime Go Mobile Tumblr. LA Times Tumblr covers their city in a way that even non-Angelenos will find useful.
• WNYC’s Transmitter: Points off for not being “Transmittr,” but this blog overcomes by providing great insight into the day-to-day workings of New York’s great public radio station. Public radio is especially well-represented on Tumblr, with really nice blogs from NPR, NPR Fresh Air and Public Radio International, to name just a few. 
• The Sunlight Foundation: Truth in advertising—this is indeed, as the tagline says, “the super sweet Tumblr blog of the Sunlight Foundation.” Great infographics equal compelling, easily rebloggable journalism on Tumblr.
• The 20 New York: Twenty New York Tumblr users blog about the local news of the day. An interesting, unique use that integrates Tumblr with NBC’s local TV stations. 
• Al-Jazeera English: An excellent source of world news, with an emphasis on the Middle East, that is especially useful at a time when it is still difficult to get Al Jazeera’s television coverage in the U.S. 
• GQ Eye: The even-more fashionable cousin of one of our favorite media Tumblr blogs, GQ Eye is a men’s fashion blog that isn’t afraid to have fun with the conventions of men’s fashion. 
• The Guardian: The UK newspaper is one of the most innovative in the world when it comes to the social Web, and their newly-launched blog is already a great source of news from a European perspective. 
• Cheat Sheet: The Daily Beast takes its most Tumblr-ready department and makes an even better Tumblr version.
• Virginia Politics: Our favorite part of this blog, aside from its nice insider view of the political goings-on of the Commonwealth, is its really well-executed integration into the rest of the Richmond Times-Dispatch Website. 
• National Journal: The DC politics publication plays well on Tumblr, which an engaging mix of its own stories, reblogs and reader interaction.

As always with posts like this, there’s the certainty that we’ve missed calling out some really great, deserving blogs. More than 160 media organizations have started Tumblr blogs in the past year, and they’re all worth a look. You can find many of them featured every day on the #News tag page; watch for more tools to discover excellent blogs in the days to come.
