Here is a portion of the story from Tuesday's news conference:
"We want to be world class and cutting edge in everything we do," said Joshua Harris.
The backdrop featured giant red banners from the Sixers' five conference champions, with the 1966-67 and 1982-83 title teams in the middle.
The Sixers reached the NBA Finals once (2000-01) in Comcast-Spectacor's 15 years as owners.
"I can assure you we will be active, long-term owners who care deeply about this team," Harris said.
