I agree with James's suggestions, and I'd like to add a few more Chromecast apps to the list. First off, "YouTube" is an obvious choice. It's a versatile app that provides an endless amount of content across various genres, including music videos, tutorials, vlogs, and more. "Netflix" is another must-have app if you enjoy streaming movies and TV shows. With a large selection of titles and the convenience of casting them to your TV, it's perfect for cozy movie nights. Additionally, if you're a sports fan, "ESPN" is a fantastic app for live sports events, highlights, and news. It covers a wide range of sports, ensuring you won't miss out on any action. Lastly, I recommend "TED" for those who love inspiring talks and thought-provoking discussions. The app allows you to stream TED Talks directly to your TV, providing an immersive experience.
