YouTube TV is adding seven new basic cable networks owned by Time Warner/Turner Broadcasting to its lineup along with NBA TV and the MLB Network.

The new TW/Turner Network channels — TNT, TBS, CNN, truTV, Cartoon Network, Adult Swim and Turner Classic Movies, along with more sports programming, will also mean a $5 a month rate hike for the streaming service, effective March 13.

Existing YouTube TV customers and those signing up before the rate increase takes effect will be spared the price increase, paying $35 a month for the service instead of the $40 rate charged new customers next month.

YouTube TV has focused much of its attention in the last year on getting local broadcast stations on its lineup, and now has a complete assortment of NBC, CBS, ABC, and FOX affiliates in dozens of TV markets. One of the reasons cord-cutters are reluctant to cancel their cable subscription is the loss of local stations, but YouTube TV has managed to overcome that roadblock for many subscribers.

The service has spent much of its annual budget on sports channels, which are usually the most costly basic cable networks. The addition of Time Warner, Inc./Turner Broadcasting cable networks came as a result of subscriber demand. Time Warner, fighting the Department of Justice over its proposed acquisition by AT&T, will likely use the new agreement as additional evidence the company is not withholding popular cable programming from AT&T’s competitors.

YouTube TV offers a 7-day free trial, after which subscribers are charged $35 a month. If interested in the service, now is the time to subscribe before it costs $60 more a year.

YouTube TV, an online streaming alternative to cable television, now reaches 50% of U.S. residents after the company introduced local TV service in 14 new markets.

The latest additions allow customers to view most local ABC, CBS, FOX, and NBC stations as part of their subscription. But YouTube TV has not yet signed agreements with all of those station owners, so some cities will continue to have only on-demand access to FOX network shows for the time being.

The newest cities added:

• Florida: Jacksonville (inc. Brunswick, Ga.), Tampa-St. Petersburg, Sarasota, West Palm Beach-Ft. Pierce
• Kentucky: Louisville
• Maryland: Baltimore
• Massachusetts: Boston
• Nevada: Las Vegas
• Ohio: Columbus, Cincinnati
• Pennsylvania: Pittsburgh
• Tennessee: Memphis, Nashville
• Texas: San Antonio
• Washington: Seattle, Tacoma

The service costs $35 a month and includes a feature-limited DVR, which in certain cases does not allow customers to fast-forward past commercials. The service also recently added two new channels to its lineup: Tennis Channel, and for Boston-area residents only: NESN, a regional sports network.

An additional 17 markets are expected to be online before the end of summer:

• Alabama: Birmingham
• California: San Diego
• Connecticut: Hartford, New Haven
• Colorado: Denver
• Indiana: Indianapolis
• Michigan: Battle Creek, Grand Rapids, Kalamazoo
• Missouri: Kansas City, St. Louis
• North Carolina: Triad Region (Greensboro, High Point, and Winston-Salem), Raleigh-Durham
• Ohio: Akron, Cleveland
• Oklahoma: Oklahoma City
• Pennsylvania: Harrisburg, Lancaster, Lebanon, York
• Texas: Austin
• Utah: Salt Lake City
• Virginia: Newport News, Norfolk, Portsmouth
• Wisconsin: Milwaukee
