Flippity.Net allows you to turn a Google Sheet into a Quiz Show. All you need to do is download the template, make a copy, and then edit the Sheet to your hearts content.
Two features that i think are awesome are inserting an image and YouTube video. To insert an image you simply insert [[Image: followed by the URL of a picture you find on the web followed by ]] and for a video a video insert [[ followed by YouTube's "Share this video" link followed by ]]. It is important to remember it is not the YouTube address in the address bar but that shortened share this video url.
I love this because the data stays on Google Drive not some third party site. One could edit this for a variety of content areas and its technology lite. The only technology needed is a Chromebook and a projection devices. The teacher quickly determines if the team got the correct answer and the Quiz Show continues.
