They still issue plenty of them and at least now they are generally meaningful. But the thing is, they have ZERO impact on company revenue and earnings, ZERO. Customers don't read PRs, only investors and traders read them.
Think of the products you buy, do you read GM or Ford PRs when you are car shopping, do you read Purina PRs when you are looking for dog food, or General Mills PRs when cereal shopping, or Honeywell PRs when looking to upgrade the Tstat, or Dell PRs when looking for a new laptop, or Walmart PRs before going to buy stuff?
PRs mean nothing to a company's performance, they mean a wee bit to investors and shareholders.
