It's a program that allows you to pick what you want to watch.. such as news, sports updates, mtv, etc...there's a lot to choose from. Some podcasts are only in audio, some are with video. All of the podcasts are clips, lasting from a couple minutes to an hour+. I never really have time to watch tv, so I just watch news and sports since they mainly focus on top headlines that are mostly updated daily.
