The strongest cable show was AMC's "The Walking Dead." Its midseason finale, in November, reached 14.8 million people.

Big numbers, right?

Try this one: 24.79 million.

That is the number of people who, on the evening of Jan. 26, 2015, and over the next 24 hours, watched a video broadcast on their phones depicting the sights and sounds of New York's "Snowpocalypse."
