I was on the Disney Magic for the NBA finals a couple of years ago, and they showed the games live in O'Gills even though they were in the middle of the night.
This might not have any relevance, but I was on a Carnival Mediterranean cruise during the World Cup in 2006, where they broadcast the final match on the big screen above the pool (many people skipped MDR dinner and ate al fresco to watch, lots of Italy fans with flags on board, Italy won, we cruised into Venice the next day and found tons of world champion merch and celebrations, it was pretty special), and on a Royal Caribbean Baltic cruise during the World Cup in 2010, where they broadcast the final match live in the main theater.
