The first comprehensive guide to humour in the age of the internet and social media, this book makes the reader laugh (for the examples) while also engrossing them for its rigorous scholarship.The book shows how humour has changed since the advent of the internet: new genres, new contexts, and new audiences. The book provides a guide to such phenomena as memes, video parodies, photobombing, and cringe humour. Included are also in-depth discussions of the humour in phenomena such as dogecoin, the joke currency, and the use of humour by the alt-right. It also shows how the cognitive mechanisms of humour remain unchanged. Written by a well-known specialist in humour studies, the book is engaging and readable, but also based on extensive scholarship.
