In January 2005, the building was officially renamed "Telusphere" as part of an agreement where Telus gave a $9-million donation in return for the naming rights to the building. This new name proved universally unpopular. In mid-2005, the name of the science centre was changed to "Science World at the Telus World of Science". The brand "Telus World of Science" was used for several other science centres in Calgary and Edmonton. The naming rights agreement ended in 2020, with the science centre dropping "Telus World of Science" from its name. During this period, the name change did not affect the nearby Main Street–Science World SkyTrain station.
