Anchor and Synth have contributed to the proliferation of podcasts in the last few years. The ways that we can find and listen to podcasts has also increased substantially in the last few years. That's why Common Craft has released a new version of their popular video, Podcasts Explained by Common Craft.
Podcasts Explained by Common Craft explains what podcasts are, why they are popular, and how to subscribe to podcasts.
If you've considered creating your own podcast or podcasting with your students, take a look at the tutorial videos that I have produced on the topic. You can also find a list of ideas for classroom podcasts right here.
Disclosure: I have a long-standing, in-kind relationship with Common Craft.
