Avago is a chip manufacturer headquartered in North San Jose off of Trimble. They are buying Broadcom--one of their competitors--for $37 Billion. That is Billion with a "B" not a typo. The new combined company will be worth over $77 Billion and instantly become one of Silicon Valley's largest companies.
Broadcom is based in Irvine but has offices in Sunnyvale, Santa Clara, and San Jose. Given the large amounts of land in North San Jose well-suited for manufacturing companies, I wouldn't be surprised to see the new company consolidate all of their Silicon Valley operations in San Jose at some point in the future.
