Whether the 24-hour Los Angeles network becomes as popular as NY1 remains to be seen. Los Angeles is not exactly hurting for local television coverage, but Spectrum insists it is carving out a different space from local news networks like KTLA or KNBC.

“We’re not going to try to compete chasing in a helicopter with the same type of scenes they would,” said Mike Bair, executive vice president of Spectrum Networks who will oversee the new network.

Mr. Bair said that 125 people would be hired for the newsroom and that they were already more than halfway through staffing up the network. The new channel — he would not reveal its name — will be headquartered in El Segundo, near the Los Angeles International Airport and The Los Angeles Times’s new headquarters.

Spectrum has several local news stations around the country, including in Florida (Orlando and Tampa) and Texas (San Antonio and Austin). Mr. Bair said that the local news stations are very popular and “create a higher level of retention” for the cable service.

In November, around 1.5 million Los Angeles Spectrum homes will get the new channel.

“We don’t have to worry about two-minute sound bites,” Mr. Bair said. “If an interview takes three or four minutes, we stick with it. We’re more likely to cover much smaller stories, neighborhood-based stories than you’d see in other markets.”
