Not totally convinced about the printing press example (expensive, technical). The biggest presses, with the longest reach (daily newspapers) were often owned by the richest people.
What's unique now is decentralized + extreme potential reach. Or it was. Now we have to consider bias in the algorithm that sticks stuff in front of us and is, I suspect, the modern equivalent of those daily newspaper presses.
