SAN FRANCISCO: Quarterly results from Alphabet Inc and Facebook Inc provided fresh evidence this week that the digital advertising market is effectively a duopoly, a dynamic with deep implications for two of Silicon Valley's titans.
Alphabet, the owner of Google and YouTube, and Facebook, the world's largest social network, each produced billions in profits during the most recent quarter and enjoyed steep revenue increases, while smaller rivals such as Snap Inc and Twitter Inc struggle to maintain growth and reduce losses.
