Google is launching an Ads Transparency Center. The “searchable hub” rolls out to global users in the coming weeks and lets anyone look up who’s behind an ad, which ads an advertiser ran and where across Google Search, YouTube and the Google Display Network. Additional details are provided for political ads, including the amount spent, number of impressions and any location targeting criteria. In 2020 Google began requiring that advertisers verify their identities, and a year later began letting users access some ad info, but its transparency move follows Facebook’s similar offering, which launched in 2019.

Apple has acquired WaveOne, a Mountain View-based startup that has been developing AI algorithms for video compression. Cupertino has been mum about the purchase, but the deal reportedly closed in January, and WaveOne employees are said to have been absorbed into Apple’s machine learning groups. WaveOne’s codecs use machine learning to squeeze more picture out of less bandwidth, including optimizing for signal interruptions, so the picture doesn’t freeze or disappear, making it ideal for mobile. As Netflix and YouTube tout picture improvements, WaveOne could potentially advantage Apple TV+ and a mixed reality headset. Read more

Amazon has opened Sidewalk, its low-power, wide-area network (LPWAN), to developers. Introduced in 2019, Amazon’s early focus was using Sidewalk to optimize Ring cameras and Level smart locks. The company quietly extended coverage to what it says is 90 percent of the U.S. population, and indicates it is now ready to connect “the next billion devices.” Sidewalk can be useful for a multitude of IoT devices that need Internet connectivity yet can’t always rely on a robust four-bar signal, or just don’t require a lot of bandwidth or power.

Substack, the web-based publishing and discovery platform, has opened an investment round to its writers and potentially other retail investors. Founded in 2017, the company has already raised more than $85 million, most recently from venture firm Andreessen Horowitz and entrepreneur Audrey Gelman. But last year, in a rough economic climate, it reportedly came up dry and is now asking the many writers who rely on it to put skin in the game. Based on early response, Wednesday’s announced goal of $2 million was upped to $5 million the next day. Read more

Elon Musk and Steve Wozniak are among a group of more than 1,100 tech leaders, researchers and AI stakeholders who have signed an open letter calling for a pause on “giant AI experiments.” The missive, published by the Future of Life Institute, warns of “profound risks to society and humanity” that could be caused by an “out-of-control race” to develop and commercially deploy artificial intelligence systems “that no one — not even their creators — can understand, predict, or reliably control.” Other signatories include politician Andrew Yang, Skype co-founder Jaan Tallinn, Pinterest co-founder Evan Sharp and Stability AI CEO Emad Mostaque.  Read more
