Recorded audience laughter and applause have been a staple of television comedy since early sitcoms used live studio crowds and later laugh tracks to guide viewers at home. As editing software became accessible, creators lifted these short crowd reactions for online videos, memes and streams. The laugh plus clap combination works because it does two jobs at once, marking a line as funny and then rewarding it like a performance. It remains popular for ironic edits too, where an exaggerated crowd response makes an ordinary or awkward moment feel absurdly important.
