Time Warner Cable is "hard at work at a cloud-based [TV] guide experience,' but willing to allow third parties to create interfaces for it, says president and COO Rob Marcus. The executive revealed the information at an investor conference in New York earlier today. The catch, Marcus elaborates, is that Time Warner isn't willing to forsake the "customer relationship," meaning that it wants people to know TV is being delivered through TWC instead of a device maker or any other company.
