The BBC is producing a series of 100 “podcasts” which explores the history of the world through the lens of 100 different objects. Each episode is about 15 minutes long, and while you can subscribe to the series for your iPod or on iTunes, you can also listen to each episode individually on the web: thirty of the planned one hundred episodes are now available.
One interesting episode focuses on the Clovis Point. They mainly give weight to a Clovis First model of the first peopling of the Americas (including a bizarre quote from Gary Haynes to the effect that yes, there is older material than Clovis but nonetheless Clovis is first), but they do also offer an indigenous perspective which is unusual.
