Why don't they use smelling salt anymore?

I've been watching like mad of 'old time' movies lately that involved someone passing out and someone reviving them near smelling salts. I'm purely curious why they don't use them anymore.Why don't they use smelling salt anymore?
They may not use them in the movies...but they do maintain them on ambulances and in ER's. They hold thier rare application, but they own been replaced as the first entry to do by the ABC'c (airway, breathing, circulation) of Basic Life Support...Is the airway obstructed? Are they breathing? Do they have a pulse? People purely don't "faint" anymore. When they fall out, they go down out!
BECAUSE NOW WE JUST SLAP THE SH*T OUT OF THEM! ,LOL
NOT SURE, BUT SMELLING SALTS ARE JUST AMMONIA, IF I REMEMBER RIGHT. THEY ARE IN MOST FIRST AID KITS.
Sheesh! have you ever smelled those things? They sting!!
They still do.it's not smelling salt it is ammonia..it once seemed close to almost everone had a faint spell at one time or another...some acted like they faint and the ammonia fumes burnt their proboscis and eyes to the point they could hardly caught their breath so they never tryed to carry attention again by pretending to pass out. Now writers won't write any faint woman in to a script at the moment.
