I have been going around here and there in search of material for this blog and I always come up with a best of article from many of the well known sci fi /fantasy sites. You know the top 100 , 50 , 10 , or what ever tv shows , movies , or books. As usual I agreed with some and disagree with others like most readers probably do. Most of these list are subjective to personal viewing pleasures and other criteria. Basically they are fun to read and that is all that matters. So scanning at a bunch of these best of blogs and seeing what they had to offer. I formulated for fun a list of the top 50 Sci fi TV shows of all time. I also took into account those shows that made more of a influence on modern Sci Fi films and modern culture as well as popularity of the series. So some of these shows on the list may be obscure and were never really popular but a great many would agree with me that they had a huge impact on society whether it be in entertainment or in culture.

One other note. If you noticed I linked everything up to Wikipedia and quoted discriptions from wiki and not some show sites or fan sites. Reason being is most show sites and fan sites dissappear after a while but the wiki page should remain for ever and carry updated links , news , and descriptions of the  show .
