Social media companies including Snap, Twitter Inc TWTR.Nand Meta Platforms Inc META.O, which all earn the majority of revenue from selling digital advertising, are facing a weakening ad market due to record-high inflation causing brands to reign in their marketing spending. Snap's shares dropped 25% last month after disappointing second quarter earnings, as it suffered from weaker advertising demand than Wall Street had expected. The paid subscription feature is now expanding to more countries including Saudi Arabia, India and Egypt, for a total of 25 markets, Snap said.
