Sheryl Sandberg, the chief operating officer of Facebook’s parent company Meta, has announced that she is leaving the business after 14 years. Her departure comes as Meta faces a slowdown in advertising sales and more competition from rivals such as TikTok. Ms Sandberg, whose husband died suddenly in 2015, is getting re-married this summer. She said she planned to leave the company in the autumn but would remain on the board. Ms Sandberg joined Facebook when it was still a small company led by Mark Zuckerberg, a then-23 year-old Harvard dropout. A veteran of Google, she helped turn its advertising business into a profit powerhouse, as the company grew to include Instagram, WhatsApp and Messenger. Is Facebook loosing its popularity ?
