Highlights From Silicon Valley’s Extravagant Holiday Parties

Some technology companies are starting to face leaner times, but you wouldn't know it from the holiday parties happening around Silicon Valley. While companies often take care not to advertise their parties publicly, word tends to leak out via hyper-connected employees.

Here's a taste: Dropbox rented the Masonic music venue in San Francisco for a live show with indie-pop artist St. Lucia. It hasn't been all cheer for the cloud storage company since Fidelity Investments and BlackRock wrote down the value of their holdings this year. Yahoo!, which recently reversed its planned Alibaba spinoff and faces a potential proxy fight, held a Roaring Twenties-themed bash. And Twitter, which cut staff in October, put up tents and a DJ stand on the AT&T Park baseball field where the San Francisco Giants play.
