Advertising relationships are often about the people who promote them. But when you are as large as Facebook, relationships are about money.On Wednesday, Facebook’s head of global advertising sales Carolyn Everson stated that she was leaving the company after more than a decade. A few months ago, Facebook’s revenue chief David Fischer stated that he would be leaving the company later this year in a Facebook post. These exits have led some to be concerned about the impact on Facebook’s revenue chief David Fischer stated in a Facebook post that he would be leaving the company later this year, for example, Ms. Everson played a large role in keeping major advertisers on Facebook’s platform, despite civil rights-oriented boycotts of the social network, The Wall Street Journal reported.Such relationships may be irreplaceable at a smaller company but are perhaps less important to a platform as large as Facebook. Its legacy Blue app alone is used by roughly 36% of the world’s population monthly, while its wider family of apps are used by almost 44%. That number of eyes has no equal.
