Leaders of Microsoft, Amazon, Facebook and Apple testify in the biggest hearing of its kind

Along with what they are saying, another subject of (some) scrutiny is bound to be the four billionaire tech CEOs’ videoconferencing backgrounds. 

Mark Zuckerberg went with the neutral white wall that he has used previously, while Tim Cook also chose a neutral background, albeit with what appeared to be a few plants on either side of him. 

Amazon CEO Jeff Bezos, the world’s richest man, joined the hearing from in front of a classic wooden bookshelf, albeit with few books on it. 

Google’s Sundar Pichai, meanwhile, was seated in what appeared to be a boardroom, with a stack of books to his left and a plant, vase and some ceramic items on his right.
