Rabbi Amnon Yitzhak held a protest against television and its products on Tuesday evening, during which 1,000 (relatively old-fashioned) TV sets were thrown into large garbage bins.
The modern "Tashlich" ceremony was held outside the Israel Broadcasting Authority's building in Jerusalem.
Rabbi Yitzhak is famous for his activities which are centered on helping Jews to become more religious or observant.
Many of the participants expressed their solidarity with the act, explaining that the television is a device which must never enter an ultra-Orthodox home.
"It's a preparation for the Messiah," said Aharon Getz, who took part in the protest.
Journalist Yaakov Ahimeir, who passed by, criticized the demonstration. "It's true that there's a lot of nonsense on TV," he said, "but in order not to watch all one has to do is turn it off… Today it's about television, and tomorrow – books? The radio? Culture?"
