HBO and Cinemax are offering a free preview this weekend, meaning non-subscribers will be able to catch the season premiere of Game of Thrones and the debut of Beyonce's mysterious HBO event Lemonade, among other programming... Even if you don't subscribe to the normally premium services.
The preview will be available from Friday, April 22 to Monday, April 25. Other programming events scheduled for that time frame include the pay-TV premiere of Jurassic World (Saturday, 6:55/5:55c), the Silicon Valley Season 3 premiere (Sunday, 10/9c), the Season 4 premiere of Veep (Sunday, 10:30/9:30c), and an encore presentation of Confirmation, the HBO original film about Clarence Thomas' Supreme Court nomination, starring Kerry Washington and Wendell Pierce (Sunday, noon/11c).
Beyonce's Lemonade (whatever it may be) is scheduled to drop at 9/8c on Saturday night, followed by World Championship Boxing. The Game of Thrones Season 6 premiere will air Sunday at 9/8c.
Sounds like you won't need your parent's HBO GO password, after all.
