News The Way I Want It

NBC4 So Calls Mobile News app has created the news tool of convenience. I can’t tell you when I last sat down in the family room to watch the news as a newscast was happening. I am more likely to have been on the go, at work or in another part of the house. Convenience with a capital C. Alerts that remind me of an upcoming story or broadcast. A traffic story or potentially dangerous pursuit are just some of the features I rely on. Lastly, it’s dependable. It’s especially valuable while traveling. Good job and thank you.

Family LOVES this app

BEST. APP. EVER. This is a must have app if you love watching SoCal car chases. You get notified the moment the chopper is on scene. Best coverage of car chases too. My kids can’t get enough of it. The reporters are always respectful and will pull back the camera view if things get too violent. I just wish that they’d leave footage of the car chase on the app so that those of us who missed a late night chase could watch it the next day. Thanks

My source for local news

Due to the ridiculously high cost of cable, I have become an avid streamer for my electronic entertainment needs. KNBC allows me to stay informed with local events when I want to or am in the mood to do so. Thanks for this option that allows me to control my time and money without being a victim to a merciless, unfeeling, greedy group of shareholders at a cable network.
