When you stream videos through your web browser, you can find them by visiting a different site altogether. Several online portals let you query multiple streaming services at once. Simply type in the name of the television show or movie you're interested in watching, and you can instantly see where it's available.
The comprehensive site GoWatchIt searches through a variety of catalogs: streaming services like Netflix and Hulu; digital content sellers like iTunes, Amazon, and Google Play; and even DVDs and Blu-rays. Enter your search term in the box at the top, hit enter, and click the matching result. You'll see your options, how much they cost, the quality of the video (high definition or 4K), and a link directly to the film or show (if it's available online). GoWatchIt also does a good job of showing related content, helping you figure out what you might want to watch next.
