Why do Democrats want to create a new media ecosystem when they already control significant media channels?

The clip suggests Democrats may not actually need to create a new media ecosystem since they already own substantial portions of existing media. Dana, a former White House advisor, points out the irony in this desire, noting "They already own the entire media ecosystem." She speculates this push might indicate their recognition that the current ecosystem is declining in effectiveness. The discussion references past Democratic attempts at media creation, specifically mentioning Air America, which featured personalities like Al Franken and Rachel Maddow. The conversation also touches on the challenge of authenticity in longer-format media like podcasts, suggesting traditional political messaging struggles in environments where truth is harder to hide over extended conversations.
