Why the early u/s now?

Well, 5 years ago when I was expecting my daughter I didn't even get my first OB appointment till 13 weeks and an u/s till like 16 or maybe later weeks. With my angel baby I got it at 7 weeks and had an u/s done that same day, I am so thankful for it cause it showed that something was wrong.
​And with this baby I will be having it at exactly 8 weeks? 
​So I'm just wondering why they're doing u/s so early now a days? 
​Is it just a safety precaution? Or just to make more money?
