International investors have been net sellers of Irish government debt over the past few months, for instance.
Over the past few decades, for instance, as the North Sea has warmed, the maximum size of haddock and whiting has declined.
Over the past few months, for instance, I've seen so much content about the next Star Wars outing that it is almost a surprise to note that principal photography only finished in November.
It can also happen when there are regulatory changes (as in the long-haul, trunk-route airline industry of the 1970s, for example) or simply because of changes in taste (U.S. consumers' retreat from cigarettes over the past 20 years, for instance).
Reporting requirements on grants have grown over the past few decades, for instance, as have rules meant to safeguard research subjects.
Over the past few months, for instance, YouTube has been allowing more and more content partners to sell their own ad inventory inside YouTube on a revenue-split basis.
The reduction in maternal and child deaths over the past 15 years, for instance, was in great part due to increased vaccine coverage and access to antibiotics.
Over the past 18 months, for instance, hundreds of indigenous boys and girls from Ecuador participated in consultations on their rights held by UNICEF through the bilingual school system - bilingual meaning Spanish and their native tongue.
