"In our core search business consumers can choose among a range of options: Bing, DuckDuckGo, Yahoo, and many more. Specialized search services are strong competitors too, including companies like Amazon, eBay, Kayak, Travelocity, Yelp, and others."
Google by far dominates the search engine landscape. It brings in 75% of all US search ad revenues, according to eMarketer. Yelp has accused Google of anti-competitive practices for years.
Google
"Competition extends across many existing and developing fields: operating systems, mobile devices and applications, voice assistants, artificial intelligence and machine learning, virtual reality, enterprise services, cloud computing, office applications, digital advertising, mobile, video sharing, and much more."
Google market share in the US: mobile devices 56%, smart speakers 24%, and digital advertising 36%.
Facebook
"Facebook faces intense competition for all of the products and services that we provide. To name a few examples, Twitter, Snapchat, Apple, iMessage, Pinterest, Skype, Telegram, Viber, Google, YouTube, and Amazon offer photo and video sharing, messaging, advertising, and other services that compete with Facebook."
Some 2.1 billion people use Facebook, Instagram, WhatsApp, or Messenger every day on average. And 2.38 billion people use Facebook each month — that's nearly a third of the world's population.
Facebook
"Today more than 92% of advertising happens off Facebook. Less than a quarter of new US online ad spend goes to Facebook."
Facebook and Google together control more than half of online ad spending and more than 80% of incremental online ad growth.
Amazon
"The vast majority of retail sales — 90% — still occur in physical stores."
That retail figure includes things like car sales and gas — stuff you'd never buy online. Even still, online retail sales have seen double-digit growth since the recession — up 12.4% in Q1 2019 compared with a year ago — while physical retail sales have mostly stagnated, up 2% in that time.
Amazon
"Amazon continues to represent less than 1% of the nearly $25 trillion global retail market and less than 4% of US retail."
Amazon's US online market share is about 38%, according to eMarketer. The next biggest competitor is eBay, with only 6%.
Amazon
"By offering small- and medium-sized businesses another low-cost way to reach consumers and by investing to support these businesses, Amazon helps make retail even more vibrantly competitive and innovative."
The EU is investigating claims that Amazon uses data from these merchants to compete against them.
Apple
"We’re proud that a good number of apps — apps like Pinterest, Spotify, Lyft, and Uber — have built incredibly successful businesses through the App Store with support from our team and the developer tools we offer."
Spotify claims Apple is privileging its own music service over Spotify's and has filed an antitrust complaint in Europe.
