Periodic period is back

Now almost on every channel there is one or more periodic shows coming up.
First it was, Prithviraj Chauhan then the trend continued with Devon ke dev Mahadev, Maharana Pratap, Jodha-Akbar, Mahabharat, Buddha and now it's Haatim!
Prithiraj was my favourite and now I follow without fail Mahadev and Mahabharat! But I'm excited about Haatim too. Buddha I wanted to see but I've read book about him so not much excited but have seen few episodes.
This is also change of preference for me. I always preferred normal love stories or family drama soaps but now I prefer periodic shows over all others! They give us knowledge I think and also tell us about our history and many more things to learn from them. :-)
