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’s Orange Plan, Philo, Sling TV’s Blue Plan, DirecTV Stream, Hulu with Live TV, Frndly TV, Spectrum TV Stream, or Spectrum TV Choice (only for Spectrum Internet customers).
The most budget-friendy way to watch Lifetime without cable is the aptly named Frndly TV for $8.99/month.
