Cyber Monday has become one of the busiest — and most lucrative — online shopping days of the year. The National Retail Federation estimates that almost 64 million people will be looking for deals today. But for shoppers with disabilities, it can be a lot harder to take advantage of sales and promotions online. A significant number of the biggest retail websites are not compliant with the Americans with Disabilities Act or Web Content Accessibility Guidelines, which lay out best practices to help make sites easier to navigate by people who are, for example, blind or hearing-impaired. Marketplace’s Kimberly Adams spoke with Josh Basile, community relations manager at tech accessibility company accessiBe, as well as a quadriplegic who uses assistive devices to help him navigate the internet, about how accessibility issues impact him when he shops online.

Actor and producer LeVar Burton is famous for many things. His iconic roles on “Star Trek” and the miniseries “Roots,” for instance. But many of us got to know him as host of the PBS show “Reading Rainbow.” His run with the show ended in the mid-2000s, but Burton is still promoting literacy for kids. He’s now the “chief reading officer” at ed-tech company Byju’s Osmo. Together, they’re launching a reading program for kids ages 5 to 7 that uses an iPad and the Osmo app’s artificial intelligence and speech recognition to help kids grasp the fundamentals of reading. That program is set to launch next month. Marketplace’s Kimberly Adams spoke with Burton earlier this year about the unique reading challenges facing kids today. The following is an edited transcript of their conversation.

Earlier this month, the highly anticipated launch of the Orion spacecraft finally happened at NASA’s Kennedy Space Center in Florida. The lift-off of that unmanned rocket was the first of a series in the agency’s Artemis missions, which aim to eventually establish a long-term human presence on the moon’s surface begin building a lunar economy including extracting precious metals and minerals to send back to Earth. But before sending humans, the agency has to test complex rockets, heat shields and life-support systems. And speed is of the essence. The U.S. and China are in a new space race to get humans to the moon. On this Thanksgiving holiday, we’re revisiting a conversation with Peter Garretson, a Senior Fellow in Defense Studies at the American Foreign Policy Council. He spoke with Marketplace’s Kimberly Adams about how the stakes are different this time around.

Artificial intelligence is commonly used in automated recruitment programs. It helps narrow down large pools of applicants using algorithms to match job seekers to open positions. But there are growing concerns that this technology is disproportionately excluding certain groups, like women, people of color or those who don’t have college degrees, even when they’re perfectly qualified.

Every minute, people upload more than 500 hours of video to YouTube — cat videos, music videos, even videos of people recording their audio podcasts. And some of those clips include content the people uploading them don’t own, like clips of music from popular songs. YouTube, and its owner, Google, have an automated technology called Content ID that regularly scans for copyrighted material — including music — and flags it for copyright holders. Marketplace’s Kimberly Adams spoke about this with Marketplace’s Peter Balonon-Rosen, who explained why the system has some musicians frustrated.

It may be called the World Wide Web, but in some parts of the world, big chunks of the web are blocked or censored. One nonprofit designed an app to get around that censorship called Lantern. The organization says its user base in Iran has grown about 400% since the start of protests there two months ago and that as much as 13% of  Iranian internet capacity is running through the app. Marketplace’s Kimberly Adams speaks with one of Lantern’s developers. Because of his work in countries with oppressive regimes, we’re using the pseudonym “Lucas” to protect his identity. He said Lantern is part of a strategy to create an “unbreakable” internet.

The crypto industry is in trouble — just look at the drama surrounding the collapse of the FTX crypto exchange, which is looking worse every day. Add to that the huge drop in value of cryptocurrencies like bitcoin and the crash of stablecoin TerraUSD earlier this year. And now regulators and investors are wondering about the next shoe to drop. Marketplace’s Kimberly Adams spoke with Hilary Allen, a law professor at American University’s Washington College of Law, about what’s next for the crypto sector. And Allen is not exactly optimistic about crypto’s future.

There is no stopping natural disasters like hurricanes and fires. So one key to surviving a changing climate is making buildings more resilient. Amy Scott, host of “How We Survive,” visits a Florida lab focused on that challenge.

The Federal Communications Commission is set to release the first round of its updated national broadband map this week. It’s supposed to show more precise and detailed information on internet availability all over the country. Advocates have complained for years the old maps were full of inaccurate data, and getting those numbers right is a big deal because this new map will determine how the government spends the $42.5 billion in the Broadband Equity, Access, and Deployment program. Marketplace’s Kimberly Adams spoke with Dustin Loup, program manager for the National Broadband Mapping Coalition, a digital advocacy group, about how the new map was developed, how the FCC will try to keep it updated and potential problems facing this updated version.

It’s been a wild ride these past two weeks with Twitter under the ownership of Elon Musk, including Musk showing up at Twitter headquarters with a sink and laying off half of the company’s global staff. Just about every day there’s a new headline about what’s happening in the company and on the platform: leadership changes, verification subscriptions rolled out and pulled back, threats to fire employees if they work remotely. Marketplace’s Kimberly Adams speaks with Alex Heath, a deputy editor at The Verge, who says Musk wants to change just about everything at Twitter, even if it’s messy.
