PBS announced today that T-Mobile has agreed to foot the bill for public broadcasting's translators to move to new frequencies, which they'll have to do in order to stay on the air after the FCC's incentive auction. T-Mobile bid $8 billion and received 45 percent of the low-band spectrum auctioned off by the FCC earlier this year. The TV channels operating on the sold-off spectrum now have to move to lower channels, share with other networks or shut down. Because the FCC isn't providing funding for translators to be repackaged, 38 million Americans, largely in rural areas, were at risk of losing access to PBS if those broadcast facilities shut down. T-Mobile's agreement to pay for the repackaging costs will keep PBS on the air in those areas.
