Ricky Gervais returns to host the 68th annual Golden Globe Awards (7 p.m., NBC). Red-carpet shenanigans begin at 6 p.m.

Much like the Miss America pageant that aired Saturday, these proceedings have evolved over the years. For decades, they were considered a slightly obscure joke, ridiculed for the fact that a tiny clique of foreign journalists called the shots. And there were more than a few hints that they could be “persuaded” to vote for certain nominees.

Around the late 1980s, the Globes were broadcast live on TBS on Saturday evenings. Relatively low-key and given little more status than the Cable ACE Awards, they seemed to be a genuine party, an event where you could watch boldfaced names have one too many and let their hair down. Since moving to NBC, the Globes have grown increasingly slick and fashion-conscious, one more lockstep in the forced march to Oscar Night.

• It has been suggested that people who consume marijuana are frequently beset by cravings for snacks, a state known in stoner parlance as “the munchies.” The two-night special “Drugged” (7 p.m., National Geographic, concludes Monday) examines the impact of certain narcotics on the body. A part of the series “Inside the Living Body,” “Drugged” explains why smoking marijuana makes one’s eyes red and why cocaine gives some people a feeling of invincibility, and how and why ecstasy triggers feelings of emotional warmth and sociability. (Not to mention lowering one’s resistance to nightlong doses of dreadful music.)

• “Scandalous” (9 p.m., TLC) looks at disgraced minister Ted Haggard and his family as they prepare to open a new ministry in Colorado Springs, Colo.

Once the head of the National Association of Evangelicals, Haggard was seen as a major force in both religion and politics. Knocked from his perch after revelations of dalliances with a gay prostitute and methamphetamine abuse, Haggard has been down but not out. And while he may have licked his drug demons, his addiction to cameras continues. This is at least the second documentary (including Alexandra Pelosi’s 2009 HBO film “The Trials of Ted Haggard”) to follow his rise and fall and stabs at redemption.

• The lavish Showtime series “The Tudors” moves to BBC America with a marathon showing of seasons one and two, beginning at 8 a.m. today. “The Tudors” will air regularly at 9 p.m. on Tuesday.

• Bill’s election victory and loss of privacy loom large as “Big Love” (8 p.m., HBO) begins its fifth and final season.
