Which tier do I need?
Several of the services offer packages with different channel lineups and prices. If a specific channel is a must, make sure the package you are considering includes it.
What else would I need to buy?
You may be able to patch gaps by buying stand-alone services like CBS and HBO. To enjoy the services on bigger screens, you will need a device like an Apple TV, Roku, Amazon Fire Stick or Google Chromecast.
Can I watch my favorite sports teams?
All of the services offer the basics for sports fans, including ESPN, ESPN2, FS1 and FS2. But the availability of regional sports networks, or the channels that frequently show Major League Baseball, N.B.A. and N.H.L. games, varies by market. Check the service’s website to see what is included. You will also need to check on the availability of channels that occasionally feature live sports, like TNT, NFL Network, NBA TV, Big Ten Network and SEC Network.
