When Mattel purchased HIT entertainment, they pulled Thomas from PBS, and moved it to Nick Jr. After the creation of the CGI Bob flopped, the entire series was pulled from PBS. Qubo aired it during their final year of operation (each episode was 10 minutes instead of 30).
The original Bob was much better than the reboot. Mattel only made one season, then abandoned HIT entertainment's entire library completely.
There was supposed to be a reboot of Barney, but that hasn't happened yet.
Personally, I hope Bob, Barney, and Thomas are sold to another company so they can come back again.
