I'm only tangentially aware of LFR, but wasn't there some overseer change? A shift in the general management?Living Forgotten Realms wasn't replaced. It continued to run alongside D&D Encounters. However, it's fair to say it wasn't supported as much as D&D Encounters.
It also wasn't particularly popular, likely a combination of the 4E rules and the adventure content.
Same company ran Living Greyhawk for eight years. D&D Encounters ran for four years.
I know the program got moved off the WotC site
