‘Tweet for a Read’ is a wearable bookmark equipped with a light sensor on the bottom, a timer and a nano computer with a wi-fi chip on the top. Every time the book is closed, the sensor detects the blackout and starts a countdown. If the book isn’t opened after a week the nano computer logs on a wi-fi network and sends a tweet message to the reader featuring real phrases from the specific author. Since social media in Brazil is mainly accessed via smartphones (close to 80% of all access) the tweets reached readers right in their pockets. The bookmark keeps sending new tweets until the book is opened again.

‘Tweet for a Read’ generated worldwide repercussion and over US$ 2,1 million in earned media, despite being a product available only in Brazil. There was even a 5+ minutes coverage on Brazilian main news channel GloboNews with journalists in different parts of the globe discussing the idea live. ‘Tweet for a Read’ was pointed as one of the “Top 10 Innovation and Advertising Ideas” in 2014. And most importantly: made more and more readers go back to reading books.
