The cancellation is likely a result of CBS simply not wanting to pay for another season of 2 Broke Girls.
The network doesn’t own 2 Broke Girls, yet still has had to cover the cost of production due to how long it has lasted on CBS.
Deadline reports that CBS was looking to share in the profits with WB, but the network and the studio were not able to hammer out the details to both parties’ satisfaction.
Meanwhile, Warner Bros. TV has made off well with the series over the years with syndication sales to other networks, landing a lucrative deal with TBS that scored them $1.7 million per episode.
