Breaking Bad creator Vince Gilligan said illegal downloading of the US drama helped increase its popularity.
"The downside is a lot of folks who worked on the show would have made more money, myself included, if all those downloads had been legal," he said.
According to Torrentfreak.com, the final episode was illegally downloaded more than half a million times.
His comments were made while he was talking about the final series to Newsbeat's entertainment reporter Nesta McGregor.
