Pushing implies that data is sent by the server without clients explicitly requesting it.
Pulling is when the client requests data explicitly.
I get notifications pushed to my phone by Apple.
I pull YouTube videos.
YouTube doesn't suddenly decide to "push" random videos to my phone in the middle of the night.
Similarly, Netflix doesn't "push" videos to their customers.
