The 2018 Cannes Lions festival was streamlined, focusing on quality over quantity by reducing the event from eight to five days and limiting award categories. BBDO excelled, winning network of the year and a record 99 lions, including multiple grand prix awards, while emphasizing the importance of creativity in advertising. Notable winning campaigns included 'Trash Isles' by LadBible and 'The Talk' by P&G, both addressing significant social issues and resonating with audiences.
