[3] After leaving school, Haffa, who grew up in Pfaffenhofen, started his apprenticeship as a wholesaler and salesman with a BMW dealer, then worked as a sales assistant at IBM from 1973 onwards.

In 1989, Haffa became self-employed and, together with his brother Florian and TV mogul Haim Saban, founded the EM-Entertainment Munich, Merchandising, Film und Fernseh GmbH (EM.TV).

With the stock exchanges on October 30, 1997, a spectacular rise from EM.TV began: the share price of 0.38 euros followed a record high after the other, also by the establishment of Junior TV at the end of 1998 together with the troubled Kirch Group.

The brothers Thomas and Florian Haffa had sold a large part of their EM.TV shares in good time before announcement of the negative news and the strong price decline.

[7] In 2004, an investor group within Thomas Haffa, transferred the operative business of the insolvent commercial vehicle company Kögel Trailer in Ulm.
