Boston Celtics unveil new jerseys with GE advertising patches. Bill Sikes/AP The Toronto Raptors are the latest team to announce the addition to advertising patches to their jerseys for the upcoming 2017-18 season, announcing their partnership with Sun Life.

So far, nine teams have announced the addition of ad patches and certainly more will come as we get closer to the season. While we don't know how much every team is making off the patches, the Warriors would reportedly command $15-20 million per year.

Some teams have opted for team-color-friendly patches. Some teams have formed true two-way partnerships with their ad patches promoting a business that the team also works with off the court. And one team has even chosen to promote a charity with their ad patch.

Below is a look at the partnerships that have been announced so far.
