On April 20, 2007, as part of CBC Radio 3's 100th podcast, a weekly video podcast was introduced. The new video-based podcast, R3TV, revolved around the personalities at CBC Radio 3 and featured a particular artist each week, who provided commentary for the podcast and had their music videos featured in the show. R3TV was also available as a channel on Internet television services such as Joost, YouTube and Miro Media Player.  In 2011, CBC Radio 3 sponsored its first documentary movie, Winning America, about Canadian band Said the Whale. The movie was directed by Brent Hodge and Thomas Buchan, and produced by Jon Siddall, Brent Hodge and Sheila Peacock. It first aired on July 23, 2011 on CBC Television in British Columbia, and then nationally on April 2, 2012.  After the success of the first film, Radio 3 decided to do a second documentary movie called What Happens Next? about Canadian musician Dan Mangan. This movie was produced and directed by Brent Hodge and Jon Siddall. It aired on CBC on August 25, 2012 in BC, and then again nationally on October 20, 2012.  Radio 3's next foray into video was in 2013, with the web series The Beetle Roadtrip Sessions. It followed host Grant Lawrence across Canada visiting various musicians and other personalities along the way, including The Darcys, Hollerado, Sam Roberts, Theo Fleury, Hawksley Workman and others. It was also directed by Brent Hodge. The Beetle Roadtrip Sessions won the award for Best Original Program or Series produced for Digital Media - Non-Fiction at the 2nd Canadian Screen Awards.
