In the 1930’s, the Western Exchange Mart in San Francisco was a copy of a mart and building in Chicago. Twitter occupies this grand old building now, and 20 9th Street would have been on the left of this building – where it says 1947. This means they would have been in some other structure that used to be next to the San Francisco Mart.
Two significant things happened on this block – Speed-X was located here, as was radio station KSAN.
The entrance to the “Twitter Building” where I am working on contract
The radio tower of KSAN – 1450 kc seen from the back of the building – before it moved and became “The Jive 95” on FM
The serendipity is really cool – I like such little surprises – it makes the daily grind all that more interesting. I know my time is short at this location – but while I was there a few historical things seemed to pop up out of nowhere.

It looks like in the late 30’s they moved to Jessie Street – about 3 blocks away.
