Hi big deal.
I am guessing they see TV and internet as another way to reach people in addition to posting signs for people to show up at a location.
Also, I am not sure they are doing this for public relations to the non Jewish world, although if someone feels that is their place, then I hope they do that job well.
I recently attended a gathering for Project Extreme, where Rabbi Avraham Twerski spoke. While I am not saying Rabbi Twerski endorsed or did not endorse the use of those vehicles, he mentioned the staggering number of young Yidden from frum homes who are “out there” in non frum society.
When you add the numbers of non frum Jews in the world, it is safe to assume the numbers that need to be reached are over on the high side of the 90% range, and that maybe using these outlets is not such a bad idea.
