Microsoft is finally making the Skype group call free for all users. Skype group call allows video calls with up to 10 people using PC's or Macs. Skype's Phillip Snalune says, "In the future, we’ll be enabling group video calling for all our users across more platforms".
This service was previously offered as a part of Skype Premium service for $8.99 monthly subscription, which included some free calls along with a larger package. A day pass for an individual to access group video calling and Skype Premium was $4.99.
