I love HBO Go, which allows you to watch all the previous seasons of a show so you can fully appreciate the new episodes. I only recently got HBO after many years and I used it to catch up on "Game of Thrones," "The Newsroom," "Boardwalk Empire," "Girls" and "Veep." I likewise recently got Showtime after many years, but it's been much harder to catch up on "Dexter," "The Borgias," and "Shameless. I have to buy the episodes or wait for a marathon to record them. pia. I still haven't seen the first season of "Homeland." Time Warner provides HBO Go, but not Showtime Anywhere, does anyone have an idea why this is?
