DraftKings will host sports watchalong parties in Boston and publish a dedicated television advertisement to mark its entrance into the Massachusetts mobile sports betting scene.

The Bay State opened to retail sports betting at the end of January, but mobile bettors have had to wait until Friday to bet online.
The “Bet Local” advert will feature celebrities such as David Ortiz and Zdeno Chara.
Meanwhile, DraftKings will also host a ceremonial bet celebration with CEO and co-founder Jason Robins.
Robins said the launch in Massachusetts, where DraftKings was established, marked a “major milestone for our company.”
Massachusetts will become the 21st US state in which DraftKings operates its mobile sportsbook.
