Anecdotal sources suggest that the contract between Spike TV and RTM expired and initially Spike TV decided not to renew.
After seeing the huge ratings fall the first few weeks of December they have seen the error of their ways. So starting on Sunday, January 5, 2014 Spike TV will have all 4 shows under the new name and format:
Only on Sundays you can watch all four shows twice, CBS sports will air them from 6-8 AM ET and Spike TV will have them from 9-11 AM ET/PT. Spike TV has renegotiated with RTM productions and they will air the new shows, but only on Sunday mornings.
