We sweat more in the summer, but the chill makes our heart race. But the truth is there’s virtually no difference between the calorie burn in the summer and the winter.

The only extreme temperature that makes a difference is when you’re so cold you’re shivering. When you shiver, your muscles start clenching to generate heat, and you burn nearly four times more calories than usual.

NBC started this practice in fall 1994 with a strategy called NBC 2000, designed to keep viewers from channel-surfing. They created the squeeze.

The people who work on a show negotiate their title and credit position with the people who create the shows. But when the networks buy a TV show or a movie – to put it on CBS, for instance – those contracts leave the ability to squeeze those credits in the hands of the network.
