$rootScope.$emit flows up to $rootScope and $rootScope.$broadcast flows down the scope to $rootScope and all $scope's in angularjs. I am still confused of what exactly to use for angularjs loader indicator .

can you explain a little better what the question is exactly? – Yaron Schwimmer Jun 25 '15 at 11:54

$rootScope.$emit only lets other $rootScope listeners catch it. This is good when you don't want every $scope to get it.
$rootScope.$broadcast is a method that lets pretty much everything hear it.
