Starting half an hour after Shabbat ends, one may listen to news broadcasts produced by Jews, since sufficient time has elapsed for the producers to have collected the material and write the stories after Shabbat. However, one who listens to the news immediately after Shabbat transgresses the prohibition on benefiting from melakha done on Shabbat. Starting fifteen minutes after Shabbat, one may listen to other types of programs, because in that amount of time a news program can be prepared for broadcast. Even if the technicians and newscasters live far from the studio and desecrated Shabbat to travel to the studio, since the listeners gain nothing from this desecration, it is not forbidden to listen to the broadcast.
When Shabbat is over in Israel, one may not listen to broadcasts by Jews in America, since Shabbat there ends between seven and ten hours later than in Israel. Thus, one who listens in Israel would be benefiting from the Shabbat desecration of American Jews. For the same reason, one who is in Israel must wait approximately two hours after Shabbat ends before listening to Jewish broadcasts from Western Europe. In contrast, one may listen to broadcasts produced by non-Jews immediately after Shabbat in Israel ends.
One may travel by bus starting half an hour after Shabbat, as that is a reasonable amount of time for the bus driver to reach one’s stop without having desecrated Shabbat. If the bus route is so long that it is clear that the driver started the route when it was still Shabbat, some forbid riding the bus (Minĥat Yitzĥak 9:39; Orĥot Shabbat 25:62), and others permit (Mishneh Halakhot 7:50). Many maintain that there is technically no prohibition because one who boards the bus half an hour after Shabbat does not benefit from the fact that the bus traveled on Shabbat; nevertheless, they continue, it is proper to be stringent as a protective measure (Tzitz Eliezer 13:48; SSK 59:9; Yalkut Yosef 318:76).
