CID, the longest running TV show in Indian history, has now entered its 15th year. That calls for celebrations, doesn't it? Sony and the CID team have formulated a year-long campaign to celebrate the show's successful run with the slogan 15 Saal se... Soch ke aage, jurm ke peeche (For the past 15 years... Ahead of the times, pursuing crime). The campaign will kickstart with the launch of the new CID anthem.
