Mobile advertising accounted for more than half (51%) of digital advertising spend in 2016, according to a new report out from the Interactive Advertising Bureau.

Why it matters: Mobile spend has finally caught up with mobile consumption rates (which officially outpaced desktop last year), because of the increased dominance of mobile-only or mobile-majority social publishers, like Snapchat, Twitter and Facebook. In the past, many traditional digital publishers have been unable to sell enough mobile ads based on that demand, largely because screen sizes allow for fewer ads per page on mobile compared with desktop and mobile CPM (cost per thousand) rates tend to be cheaper than desktop.

Joe Biden has laid out a more concrete tech agenda whereas President Trump has focused on tax cuts and deregulation while criticizing tech firms for anti-conservative bias. That's according to a side-by-side analysis of the two candidates' tech records by the Information Technology & Innovation Foundation shared exclusively with Axios.

Why it matters: The tech industry needs to prepare for either four more years of Trump's impulsive policy approach or for a Biden administration that's likely to be critical of tech but slow to take action.

Why it matters: The concentration of wealth in a few massive U.S. tech companies has reached a scale significantly greater than it was before the dot-com bubble burst.
