In the days of the WTBTS under the presidency of Rutherford a lifetime ago, JWs hauled phonographs from door to door and played records of Rutherford's advertising speeches. A sort of early experiment with multimedia.
The idea has returned in a way. You don't have to go to Brooklyn or even a Kingdom Hall anymore to get a first taste of official WTBTS media. They now have a video that they stream out on the Internet. I'd watch it for amusement, but I don't use Real Media software.
