Whether it is on a smartphone, tablet or laptop, being able to watch live television outside your home network is pretty great. Cablevision, through the Optimum App, has been letting its cable customers do this for some time now, but it's about to get much better. The service provider today announced that it is baking the "TV to Go" feature right into its Optimum App, allowing you to have access to over 100 channels even when you're away from home. This includes both live and on-demand content, from networks such as beIN Sports, CNN, Disney, ESPN, NBC, NFL and a lot more -- naturally, access to these will be determined by which Optimum TV package you pay for. The revamped Optimum App service is available now on the web, iOS, Android and Kindle Fire tablets.
