TikTok beat out Google for the most popular domain in 2o21, according to data from web security and performance company Cloudflare's 2021 Year in Review of internet traffic.

Why it matters: Video-sharing platform TikTok rose to massive popularity in 2021. Surpassing mammoths like Google, Facebook, YouTube and Netflix in web traffic shows the speed and power of the ascent.

  • Google and Meta-owned Facebook are well-aware of TikTok nipping at their heels, unveiling video-based features like Instagram's Reels to keep up and referencing the app when accused of having too much power and not enough competitors.

Driving the news: TikTok rose from No. 7 to No. 1 on Cloudflare's ranking of top domains in 2021, and it also beat out Facebook this year in social media domains, taking its No. 1 spot.

Of note: Cloudflare says it uses "a range of data ... about global Internet traffic patterns" to calculate its rankings but doesn't make clear exactly how it arrives at its list.

  • Cloudflare also only collected data for a few months in late 2020 compared to all year in 2021, so it is not a perfect comparison.

Tech giants play the blame game

With regulators around the world looking at reining in Big Tech, the companies in the crosshairs are increasingly eager to point out their rivals' sins.

Why it matters: Investigations in the U.S. and around the world are targeting Apple, Google, Facebook, Microsoft and Amazon. To make their case, regulators need to show the companies are squelching competition — a task the tech companies may be aiding with their infighting.

The FDA said Monday it's limiting the use of two monoclonal antibody therapies as COVID-19 treatments because data indicates they're "highly unlikely" to be effective against the dominant Omicron variant.

Driving the news: The FDA revised the authorizations for Regeneron and Eli Lilly "to limit their use to only when the patient is likely to have been infected with or exposed to a variant that is susceptible to these treatments," per a statement from the agency.

Pentagon: 8,500 troops on high alert for possible deployment to eastern Europe

Defense Secretary Lloyd Austin has placed 8,500 U.S. troops on "heightened preparedness to deploy" to eastern Europe in case NATO activates its rapid-response force over tensions with Russia, the Pentagon announced Monday.

Why it matters: No decisions have been made to actually deploy U.S. forces, but the heightened alert level will allow the military to rapidly shore up NATO's eastern flank in the event that Russia invades Ukraine. The Pentagon warned that Russia has shown "no signs of de-escalating," and continues to amass troops on Ukraine's borders.
