Sling TV, the Internet TV streaming service from Dish Network, might have gotten off to a relatively slow start, but with more and more people opting out of cable and satellite subscriptions, the service's numbers could be on the upswing.Goldman Sachs analyst Brett Feldman wrote in a research report released on Thursday that the group estimates that Sling TV will have 2 million subscribers by the end of 2016, Investors.com reports. As a comparison, the service had only 240,000 subscribers as of June 30, with estimates for its subscribers estimated between 300,000 and 500,000 at the end of September. Feldman estimated the service had 346,000 "exiting Q3."If this is the case, it could make up for the subscribers Dish is losing. Feldmen estimates the company will lose 724,000 subscribers from its satellite TV service in 2016, up from the estimated 543,000 subscribers lost last year.Sling TV starts at $20 per month, offering a relatively small lineup of channels including ESPN, AMC, TBS, Disney, and Cartoon Network/Adult Swim. This is expanded on with additional groups of channels that usually add $5 per month to the customer's bill. Movie, sports, and "lifestyle" packages are among those available, and a standalone HBO option is offered for an additional $15 per month.
