It's fewer viewers not less viewer okay.
It's a countable object you are directly referencing.
You can say there's less than 5 dollars in here because it's a currency type but if you're referring to 5 $1 notes (5 separate objects) you would say there are fewer than $5 of notes here.
Use fewer when you are referring to the countable object directly.
Use less when it's indirect.
Learn the difference.
