Summary: Meta is quantitatively dominating the social media space, but YouTube is moving fast to leverage existing infrastructure with their "Shorts". As technology becomes more accessible, the landscape may fragment and large companies may not have such a large share. Meta and Google are primarily advertisers that build attractive software where ads can be served along media. Meta Platforms, Inc. (NASDAQ:META) is pushing multi-year lows, as the stock hovers around the $140 level.
