Yes, we have heard that Google bought the blocks where Gold's Venice is and told them they won't renew the lease, but nothin has trully official in print yet that I can find. Just lots of people talking about they need to find a new location in two years when Google starts to renovate the area.
That being said - Gold's Gym does not WANT to move - all is good in the location, it is one of the busiest gyms in the area, and tons of people go there. It is the mecca of bodybuilding, and people like to go there, just because it has history.
The historical aspect of it closing would be tough to many. Too many, if you are into the bodybuilding world, coming to Southern California and checking out Gold's Venice, eating at the Firehouse, and going to Muscle Beach is too cool.
It would be sad day for bodybuilding if Google forces Gold's Gym out of Venice.
