Just thought I'd let you guys know about a small development. As I was Googling upcoming movies I came across this.
I am guessing it is apart of Google.com's new search features. But if you look closely you will see along with the release date on the right, there is a remind me button. Isn't that epic?
Also when you search Labor Day or other holidays you get one as well. Allbeit this one is more specific as it mentions Google Now.
Here are a few more examples
It only works if you have Personal results turned on. So it works with movies and holidays. I wonder what else it works with. Upcoming Albums or video games? If you find any other examples tell me in the comments. :)
