Meanwhile, Twitter will Periscope its earnings this evening. It has been a year since Dick Costolo resigned as CEO and co-founder Jack Dorsey returned. But Twitter still struggles to answer the question that’s plagued its entire existence: “What is Twitter?” Dorsey’s most recent answer, “Twitter is ‘live’ ” hasn’t really stuck. Yesterday, Twitter unveiled a new ad campaign playing up its role as a political news engine with the message, “See what’s happening.” It emphasizes Twitter’s biggest selling point: No matter how aggressively Facebook, YouTube, Instagram, and Snapchat try to compete, Twitter is still the go-to place for politicians, business leaders, athletes, and Kanye West to make important announcements.

During its call tonight, I’ll be listening for questions about Twitter’s recent push into sports—the last bastion of live television viewing. Its recent spate of livestreaming deals with MLB, NHL, NBA, and NFL has prompted speculation that Twitter might be a takeover target for the likes of ESPN. At Fortune’s Brainstorm Tech conference in Aspen earlier this month, Disney CEO Bob Iger was candid in his assessment that ESPN will eventually need to move away from traditional cable packages.

Twitter’s $13 billion market cap makes such a deal feel too expensive. But maybe all ESPN has to do is wait.

In 2007, Yahoo rejected a $44 billion takeover offer. Less than a decade later, Verizon got it for one-tenth that price, a relatively modest $4.8 billion. If Yahoo’s fate tells us anything, it’s that turning around a struggling Internet asset is nearly as impossible as knowing the right time to sell.

Is there an agtech bubble? Last year investors plowed a record $2.7 billion—five times the figure in 2012, according to AgFunder—into so-called agtech startups, which are cultivating a new generation of robots, drones, soil and crop tech, sensors, and more. Nearly a dozen specialized accelerator programs have launched since 2013, and conferences now draw the likes of Verizon Wireless, Samsung, and Silicon Valley venture capitalists.

But small farmers seem flummoxed by many of the new products and services, which are often tied to complicated contracts; don’t work with existing equipment, software, or growing practices; and promise solutions to problems that growers don’t necessarily have. That concern has sparked talk of a farm-tech bubble.
