PLOT
Call for Help, also known as CFH, was a computer-themed television program that first aired exclusively on TechTV, a cable and satellite television network focused on technology, and then aired on G4techTV Canada and the HOW TO Channel in Australia. The final taped episode aired on February 26, 2007, but because the episodes were taped out of order, a number of other episodes taped during the same shooting week aired through April 6, 2007. A spin-off called The Lab with Leo Laporte aired much of the same content as Call for Help and ran on the same networks. The Lab was canceled about one year later due to low viewer ratings and the final episode aired in August 2008.
