[Neil Jones]

I wrote to Richard O'Brien and Ed Tudor-Pole in the early 00's and they both sent me lovely replies, and Ed mentioned in his that he sadly gets nothing in the form of repeat fees from the (at the time) constant Challenge repeats.

Suppose its a shame and a blessing they didn't go for a % of revenue of sales, like you sometimes used to see with film actors (First-dollar gross the practice was called). If you play your cards right with that you can make significantly more money than you would have done just being paid for the job in the first place.

But of course TV is done on significantly cheaper budgets and at a far quicker turnaround, so its probably par for the course you just get a wodge of money at the time with no further reimbursement and if it gets aired to death years later, that's tough.

I dare say that applies to the bulk of programming (not just gameshows) for the UK in the 20th century at least.
