Brazi's leading Sunday newspaper Extra has built a glass newsroom in downtown Rio to celebrate its 15th anniversary and demonstrate its newsgathering skills in a truly "transparent" way. Agency Espalhe Guerilla Marketing is responsible for the 200 square meter glass structure, named #ExtraNaRua (Extra In The Street), which is working in full view of passers-by for the whole of this week. It houses 30 journalists, editors, directors, designers and photographers, as well as a radio studio and photographic studio for magazine fashion shoots.
