Through the first full round of play, TNT’s live NBA coverage is averaging 1.92 million viewers and a 1.3 household rating, down 870,000 viewers versus its year-ago average (2.79 million) and off 28% compared to its analogous 1.8 rating. That said, TNT’s playoff ratings have largely held up during its priciest windows. Per Nielsen, TNT is currently averaging 2.56 million viewers for its games airing in East Coast primetime, down just 11% from the year-ago 2.88 million. And that’s not just geographical bias talking: 48% of all TV homes are in the Eastern time zone (versus 16% out west, 29% in the Central zone and 7% in the rugged Mountain region). East Coast prime is where it’s at.
