Like other Regions, an annual expo, called WESCON, was formed and existed over 50 years - from 1951-2005 when it was dissolved. WESON alternated between the Los Angeles area and the Bay area. At its peak in the 1980's it drew approximately 50,000 attendees.
The Region is divided into five areas: Central (CA), Northeast (NEA), Northwest (NWA), Southern SA), Southwest (SWA).There are two Councils: Los Angeles (LAC) and San Francisco Bay Area (SFBAC).
There are currently 35 Sections in the Region, listed by date of formation. Area and Council affliliation is listed in ().

Split later into TCP and an Internet Protocol (IP), TCP and IP became core components of the Internet that DARPA launched operationally in 1983.\n\u003C/p\u003E","title":"Transmission Control Protocol (TCP) Enables the Internet, 1974","link":"","lat":37.4300184,"lon":-122.1733027,"icon":"/w/images/6/6a/Purplemarker.png"}],"imageLayers":[]}
