Takashi pretty much said it all and this is kind of trivial but if you want to say "ever since", the expression would be 「それからというもの」. It think it suits the context because the expression emphasizes "everyday" as in, say, every single day.
それからというもの、毎日それを見るようになりました。
That sentence implies that something happened, and ever since then you became attracted to it that you started watching it everyday.
