The site self-describes its purpose as follows:
At Tridentine Mass TV, we wish to promote the beautiful, unchanging, reverent Holy Tridentine Mass per the 1962 Roman missal, and per the guidelines of Pope Benedict XVI's Summorum Pontificum. Tridentine Mass TV is intended to be a resource for the United States (and if wished it can be extended to Canada and elsewhere) for local groups attempting to establish the celebration of the Tridentine Mass in their parishes. Tridentine Mass TV has subdomains for local groups in various geographical regions to post news, information, etc. An example for Chino Hills, California is CH.Tridentine.TV.
