There is no broadcast, but when you are scrolling your feed you will see a selection of friends who have liked each post.
Also if you view the activity feed (in a different corner of the app) you can see what your friends have been up to. This is where you will see more explicitly "Sally, Sue, John and Dave liked a post by Mr. Famous" (and similar activity).
