NBC is extending its out-of-home reach in Philadelphia, equipping 1,200 taxis with "video screens that stream NBC10 news updates, weather, CNBC business news, and NBCUniversal entertainment to cab hoppers," writes Bob Fernandez. Previously there were 100 cabs so equipped. There are 12,000 cabs streaming NBC content -- more than half in New York City, with others in Boston, Miami, San Francisco, Las Vegas, Chicago, and Dallas.
