1) Commercial journalism has traditionally relied on advertising funding but the rise of digital media has disrupted this model as advertisers can now reach audiences through other channels like Google and Facebook.
2) The boundaries between news, advertising, and opinion have blurred online as publishers struggle to monetize their content. Readers now get their news from social media platforms rather than direct from publishers.
3) There is growing concern that personalization of news through algorithms can lead to "filter bubbles" where people only see viewpoints they already agree with and miss important or challenging information. Verifying facts is also more difficult in today's media environment.
