Maybe not in the middle of a meeting but Amazon commonly has the first half of a meeting (I've experienced as long as 20 mins) to read a document by the host altogether silently before starting. People commonly would add comments during this time. At google, doc reading is done before the meeting along with comments/replies, but during a design review, the host will go through each comment and then open a live discussion if needed. Both of these formats allow for productive meetings but it does require a culture to support it and people to write down their thoughts ahead of the meeting and share it around.
