Delhi Metro stations to get digital walls for video ads
Delhi Metro stations will soon get 'digital walls’ to play video advertisements without the audio, an official said. “ [O]nly a pen drive will be needed [then] to put ads," he added. Such walls of 12x6 feet size have already been installed at the ITO station but stations like Rajiv Chowk will reportedly have walls as large as 16x8 feet.
