Early to rise and watch TV

The number of American households that have a TV set on at 4:30 a.m. has doubled, to 16 percent, since 1995, says television reporter Brian Stelter in the New York Times. That's far less than the 44 percent of homes that have a TV on when most newscasts go off the air at 11:30 p.m., but still enough people that the 4:30 a.m. slot is the hot time for TV stations looking for a competitive edge. "In Los Angeles, every station save one already starts at 4:30 a.m., and that one, KCBS, will catch up on Tuesday," writes Stelter, who was in L.A. covering the Emmys.

Stelter tweets tonight: "Coincidentally, I was able to watch the 4:30am newscasts in NY today, aboard my red-eye flight from LA. Thx Jetblue."
