Stations that choose to participate in the live broadcast will air the 58th annual award show from 5-8:30 pm PST and 6-9:30 pm MST. Last year's Grammys received 24.8 million viewers, reported Billboard.
"We've discussed this with CBS for years, but a variety of factors came together this year, and we collectively agreed that we had the perfect opportunity to try a new model and see how viewers respond," said the Recording Academy and GRAMMY Foundation president Neil Portnow.
"I'm very pleased to share that, for the first time, west coast TV viewers will be able to watch the GRAMMY Awards live."
LL Cool J hosts the upcoming Grammy Awards at the Staples Center in Los Angeles on February 15, now airing live across the country via participating CBS affiliates and owned stations at 8 pm EST.
