NEW YORK (TheStreet) -- Apple (AAPL) - Get Report hits another snag as it moves back the launch of its live TV service to 2016. 

After several years of waiting, Apple TV fans may have to wait at least until next year for the long-rumored TV subscription service.

The company and CEO Tom Cook is now aiming for 2016 to debut its live Internet-TV service.

The negotiation talks to license programming from networks are taking longer than expected, which is causing the delay.

The company hopes to ink deals with television networks such as those owned by CBS (CBS) - Get Report and Twenty-First Century Fox (FOXA) - Get Report, but the negotiation talks between content providers and pay-TV companies often take some time.

Cupertino, Calif.-based Apple is working to find the right mix of channels to make the new service appealing to cord-cutters.

Apple is still expected to introduce a more powerful version of its Apple TV set-top box on Sept. 9 at an event in San Francisco, but users will still need a cable or satellite subscription or an antenna to watch live network television.

When its streaming service finally launches, Apple will offer a package of popular channels for $40 per month.

The average cable bill in the U.S. is about double that amount. Apple expects to boost revenue amid its slowing iPhone sales with the launch of the live TV service.

Apple designs, manufactures and markets mobile communication and media devices, personal computers, and portable digital music players, as well as a variety of related software, services, peripherals, networking solutions, and applications.

It currently has a market cap of more than $656 billion. Shares of Apple have risen more than 4% so far this year, and have gained about 18% over the past year.
