Is it me or is intrest in League dropping?

Just look at google trends: https://gyazo.com/2565aff6de39fda460ec7a501f61ddd5 Intrest was at its peak on september of 2013. I am just wondering how long this game might stay alive :) Any ideas? Discuss.

Edit: You can also see LoL growing in 2015 for a little bit because of the lcs but after that the search ammount drops slowly.
