Google Search - HD Becomes Common

Researching the development and implementation of high definition television in relation to sensory issues led me to Google  the term - HD becomes commonplace. 
I was expecting to face the usual problem when googling common ideas, choosing between the near infinite references.
To my surprise the search I entered brought me no - 0 - relevant results on the first page. 
Only what you see above. 
"When Supernatural Battles Became Common Place"
Oh Google...
What is going on in your algorithms that my search for a simply early 'oughts date range for some basic tech brought me to this adorable manga? 
I have not searched the details yet but I think I did watch the anime way back when. Before it had an English title. I must read it now to be sure. 
Cheers. 
And if you were wondering when the presence of HD screens and broadcasting began to have negative effects on those of us with sensory issues you are out of luck. 
Blame Google.
