TV feast of James Bond and other agents

James Bond is everywhere this holiday weekend. He's in Daniel Craig's big-screen blockbuster "Skyfall." He's in Syfy's Bond Movie Marathon, starting tonight at midnight with Roger Moore's "For Your Eyes Only" and Sean Connery's "Dr. No." There's more 007 action on Syfy both Thursday and Friday 9:30 a.m.-5:30 a.m. (Full lineup at syfy.com/schedule.)

And then there's TV's horde of pseudo-007 series. The Bond craze of the 1960s begot a batch of knockoffs, genre-benders and lampoons that remain cult faves. More recently, the tube's new 21st century spies have captured a whole new audience.

Or not. Remember "My Own Worst Enemy"? "Undercovers"?

They couldn't measure up to American TV's most memorable secret agents:
