There are plenty of cooking shows in the internet era, but they tend to be pre-recorded, passive affairs. The results are predictable, and you probably won't get to ask questions about the recipe. That's where YouTube veterans Steve Chen (who co-founded the company) and Vijay Karunamurthy think they can help. They've launched Nom, a service that's all about livestreams for cooking and eating. Think of it as a specialized, gastronomical take on Periscope. Individuals and whole teams can broadcast live video from PCs or iOS devices, take input from viewers (including images and videos), and schedule shows. They can even use two live cameras, if the budget allows.
