There are two ongoing shows that I am caught up in as of the most recent episode, which are Bates Motel and The Walking Dead. Bates Motel is currently in its between-seasons break, while The Walking Dead is currently going through its seventh season.
Other shows I have on the go are Game of Thrones (one season in, need to get back into it), Breaking Bad (got through the first three and a half seasons then stopped watching for some reason. I plan to start again from the beginning at some point because it's an amazing show), Lost (watched the first three seasons before it was removed from Netflix, I'll finish it eventually), Fear The Walking Dead (watched the first season, I'll probably watch the second season after the first half of Season 7 of The Walking Dead finishes), and 24 (just started watching two days ago, instantly addicted). Who knows if I'll ever finish all of these, but I do plan to, eventually.
