Tech companies with Super Bowl ads: The list included Intel, Wix, Google, and Squarespace, and others. Airbnb made headlines with its pro-immigration and diversity theme. The company bought the 30-second spot on Thursday and filmed the ad that same day with some of its employees, according to co-founder and CEO Brian Chesky.

Bonus: Intel provided 300 drones for Lady Gaga's halftime performance. The drones flew in various formations, though the sequences were pre-filmed as FAA regulations prevent them from flying above the stadium.

97 companies band against Trump's immigration restrictions: On Sunday, a group of mostly tech companies filed an amicus brief in the Ninth Circuit Court of Appeals to express their opposition to Trump's recent executive order on immigration, according to media reports.

Missing: Amazon, Hewlett Packard, Oracle, Cisco, IBM, and Palantir, among others, including Elon Musk's Tesla and SpaceX.
