In case no one had been monitoring his Instagram account in the past week, he made sure to mention his post on Twitter:
Heat fans were understandably left with mixed reactions.
Some were thankful for his time in Miami and the two championships he helped bring them, while others were upset that he jumped ship after losing their three-peat bid to the San Antonio Spurs in the NBA Finals last season.
Luisa Fernandez, television and radio host for Univision, shared kind words on James' decision via Twitter:
On the other hand, some Heat fans were upset about James' move and questioned why he would return to the team that harbored so much resentment after his decision to leave in 2010:
So what does this mean for the Miami Heat?
Without the best player in the NBA there to lead Miami into another potential championship next year, fans of the franchise are left questioning its future.
Chris Bosh came to an agreement with the Heat Friday on a five-year contract worth $118 million, according to this tweet from ESPN's NBA crew:
Though Bosh will return alongside Dwyane Wade, the Heat may not be the team they once were for a long time.
The former Big Three will be missing its alpha dog in James, who was able to consistently lead them to the playoffs every year. The stats from the 2013-14 playoffs should illustrate just how much James was contributing to the Heat:

With LeBron out of Miami, it may take a while for the team to rebuild to the point where they are once again an annual title contender.
Up north, Cleveland fans are ecstatic.
The same outraged fans who burned James' jersey following "The Decision"—like those in the following video—may now be wishing that they had held onto it instead:
Here are a few tweets from other Cavaliers fans, who are happy to have King James coming back to Ohio:
James knows his decision to return to Cleveland doesn't mean competing for another NBA title right away, but he wants to help build up the team and bring the first-ever NBA title to his home state, according to an article by James (as told to SI.com's Lee Jenkins):
When I left Cleveland, I was on a mission. I was seeking championships, and we won two. But Miami already knew that feeling. Our city hasn't had that feeling in a long, long, long time. My goal is still to win as many titles as possible, no question. But what's most important for me is bringing one trophy back to Northeast Ohio …
I'm not promising a championship. I know how hard that is to deliver. We're not ready right now. No way. Of course, I want to win next year, but I'm realistic. It will be a long process, much longer than it was in 2010. My patience will get tested. I know that. I'm going into a situation with a young team and a new coach. I will be the old head. But I get a thrill out of bringing a group together and helping them reach a place they didn't know they could go.
The future of both the Heat and the Cavs are in question following James' new decision, but of the two, Miami will probably have the most work to do in rebuilding.
The Cavs, on the other hand, will now have the opportunity to attract top talent with The King back in town.
