I can't see one on my boat -- but I would think if you search for cable cutting - you would find lots of ways folks have been watching TV over the internet without fancy gear.  Getting fast/reliable internet to you boat is another story -- There is also still TV the old way -- broadcast.

We have Dish Sat at home and bought a tailgater anteena that sits on the bow of the boat and stow it down below when under way.It only works at dock not under way or at anchor but at 350$ it doesnt cost much and works great

We have a cheap HD antenna, about $30.  It works whenever a station is in range.  They advertise up to 50 miles, but 15-20 is probably more like it.  We sail on the Upper Chesapeake and have found we can get at least one local station, sometimes 3 or 4.  Using our cell phone as a mobile hot spot also sometimes works, but not reliably and watching a movie eats up a lot of data which can get expensive

I have T-Mobile and a Visio smart TV.  Can stream Prime, HBO and others without Burning my minutes.  I can use the hotspot or just plug in my iPhone to the tv with an HDMI adapter.  This ended my futile quest for WIFI.  

I was going to spend hundreds of dollars for a WIFI setup and just needed the right mobile carrier.

Times have changed!

Connectivity and streaming varies with all wireless media.  It's an it depends on where you are and what the coverage is.

Disney in Orlando, the coverage is horrible.  Yet I did a FaceTime 7 miles offshore heading to the Key West off Ft. Myers.  I have found WIFI to be less reliable.  Satellite has its issues also.

We have an IPhone with unlimited internet/wifi so we use an apple plug and mirror it on the screen using Netflix. As long as we have a signal it works great. Sometimes it stalls a bit streaming but usually great...

We placed a 24 inch Vizio smart tv above the card table. We have unlimited data on our android smart phones, so we installed a free hot spot app called foxfi, and we use our phones to broadcast to the Netflix, Amazon, etc., apps that come preinstalled on our smart t.v. If reception is bad, we sometimes hook our phone up directly to the TV via a micro HDMI cable, which mimimizes data speed loss between devices. And if there is no data signal whatsover, Amazon recently started allowing it's members to download movies and TV shows to their SD cards on their phones...works great. We also bought a 50 mile indoor antenna that pulls in a bunch of channels here in Long Beach, many of them are broadcast in HD. We usually hoist the antenna about 6 or 7 feet up the halyard for better reception. Finally, we bought the VIZIO E-Series E241i-A1. One cool aspect of this smart tv is the stand. It is triangular and juts out just below the bookshelf cross beam above the card table, thus holding the TV in place without having to mount it. I simply tied a string around the base and the crossbeam, just to be sure.

Hope this helps--Joel S.
