Fiorentina owner Rocco Commisso says he's in charge of the club to win trophies.
The Viola have welcomed new signing Franck Ribery this week.
Mediacom was founded in 1995 and I hope it brings Fiorentina good luck," said Commisso.
We want to invest in the most beautiful city in the world and at a team who haven't done very well in recent years.
Mediacom is now the fifth largest cable company in the US, but it wasn't like that at the beginning.
I also hope Fiorentina benefit from that, but I need time. I won't say how much the sponsorship is worth, but it's a multi-million deal.
I've opened my wallet and they're using it! We have 24,000 season-ticket holders. We hope to exceed 25,000, but it's still a great success.
I thank everyone for the affection they' gave me since day one. They've mellowed me and when I returned to New York, I said I had to do something important for Fiorentina.
I met Ribery and Boateng at a hotel. Without my wife I wouldn't be in Florence, just as theirs were important in their choices.
We've done a great job to rebuild the team. I said we could lose on the field, but while working hard and giving our best like I used to do as a player."
He added: I want to be in contact with Fiorentina every day. I didn't buy them as a hobby or for business, but rather out of passion and responsibility towards the fans.
I want to invest and win things, otherwise I wouldn't be here."
