Yes, I second podcasts. I particularly like the NPR ones because the audio quality is very high (some of the more DIY ones are recorded in people's homes or offices and the sound is not as good). They have a number of non-political ones.But there are podcasts for every topic under the sun--cooking, books, gardening, etc.
In the mornings, I actually like to watch TV (streaming, not live). I am not a morning person and am not up for challenging reading or anything like that. An episode of something while I drink my coffee gives me a chance to wake up slowly.
In the title of your post you mention reading material, and I actually think blogs are great. Supposedly the blog is dead as a medium (I think they mean money-making medium) but there still seem to be plenty out there. The key is to get a blog reader like Feedly (a program that compiles feeds from lots of different blogs in one place. ) I have found a lot of great, positive content out there--one I often recommend is the content from Mental Floss magazine.
