Grey's Anatomy, Desperate Housewives, Army Wives, and many other popular TV shows have found home in the Lifetime channel.
Cable is not needed to watch Lifetime, and hasn't been for a while now. To watch it online, you can simply subscribe to Sling TV Orange, Philo, Sling TV Blue, Hulu with Live TV, DirecTV Stream, Frndly TV, or Lifetime Movie Club.
The most budget-friendy way to watch Lifetime without cable is the aptly named Lifetime Movie Club for $4.99/month.
