HaQer got it exactly right.
The Rav ZT”L had a TV in his YU apartment. He lived in Boston with his daughter and family after his wife died. He came to NY every Tuesday morning and gave a shiur in the Yeshiva in the morning and at the Moriah Shul (in the upper West Side) for the public on Tuesday nights (which is why it says “ki tov” twice on Yom Shlishi, btw). Then he gave shiur in the Yeshiva on Wednesday and Thursday and afterward went back to Boston.
In the evening the Rav would occasionally put on the TV (which I personally saw there) to see the news and in 1975 to see how the Red Sox were doing in the world series in order to engage his young grandchildren.
Apparently the Rav had no fear of losing his Olam Habah.
