Is a large share of social media advertising enough to prove monopoly?
Core argument: Facebook captures 25% of total US online advertising and 60% of the social media advertising market, a position that raises questions about whether the company qualifies as a monopolist.
Facebook holds a significant position in the US advertising market, capturing 25% of the total online advertising share and a dominant 60% of the social media advertising market. This substantial market presence raises questions about its monopolistic status, especially as the Federal Trade Commission (FTC) struggles to define digital markets where traditional consumer-derived sales metrics are ineffective. Despite its market power, as evidenced by its association with "The Social Network," legal challenges to Facebook's dominance have faced setbacks. A federal judge dismissed antitrust cases against Facebook, highlighting the complexity of proving monopolistic behavior in the digital realm. The FTC has been given 30 days to refine its arguments, underscoring the ongoing debate over Facebook's influence and the need for potential antitrust law reforms.





















Ed Comment:one thing that looks unbelievable in the vote analysis: Between 2016 and 2020, 5 percentage points more women voted for Trump and 7 points more men vote for Biden (than Clinton). These increases largely came from voters who appear to have written in a candidate in 2016. That large a share of write-ins seems hard to believe (even though I wrote in a name).
"...Both Trump and Biden were able to bring new voters into the political process in 2020. The 19% of 2020 voters who did not vote in 2016 or 2018 split roughly evenly between the two candidates (49% Biden vs. 47% Trump). However, as with voters overall, there was a substantial age divide within this group. Among those under age 30 who voted in 2020 but not in either of the two previous elections, Biden led 59% to 33%, while Trump won among new or irregular voters ages 30 and older by 55% to 42%. Younger voters also made up an outsize share of these voters: Those under age 30 made up 38% of new or irregular 2020 voters, though they represented just 15% of all 2020 voters... Biden made gains with suburban voters. In 2020, Biden improved upon Clinton’s vote share with suburban voters: 45% supported Clinton in 2016 vs. 54% for Biden in 2020. This shift was also seen among White voters: Trump narrowly won White suburban voters by 4 points in 2020 (51%-47%); he carried this group by 16 points in 2016 (54%-38%). At the same time, Trump grew his vote share among rural voters. In 2016, Trump won 59% of rural voters, a number that rose to 65% in 2020.... Trump made gains among Hispanic voters. Even as Biden held on to a majority of Hispanic voters in 2020, Trump made gains among this group overall. There was a wide educational divide among Hispanic voters: Trump did substantially better with those without a college degree than college-educated Hispanic voters (41% vs. 30%).... Biden made gains with men, while Trump improved among women, narrowing the gender gap. The gender gap in the 2020 election was narrower than it had been in 2016, both because of gains that Biden made among men and because of gains Trump made among women. In 2020, men were almost evenly divided between Trump and Biden, unlike in 2016 when Trump won men by 11 points. Trump won a slightly larger share of women’s votes in 2020 than in 2016 (44% vs. 39%), while Biden’s share among women was nearly identical to Clinton’s (55% vs. 54%).... Biden improved over Clinton among White non-college voters. White voters without a college degree were critical to Trump’s victory in 2016, when he won the group by 64% to 28%. In 2018, Democrats were able to gain some ground with these voters, earning 36% of the White, non-college vote to Republicans’ 61%. In 2020,Biden roughly maintained Democrats’ 2018 share among the group, improving upon Clinton’s 2016 performance by receiving the votes of 33%. But Trump’s share of the vote among this group - who represented 42% of the total electorate this year - was nearly identical to his vote share in 2016 (65%)...."
