PA services became more mainstream and profitable during this decade. The widespread use of tablet computers and cell phones, and smartphones and their ability to access the Internet aided the immediate and more effective implementation of help PA activities. The introduction of flash drives and cloud computing fostered the aggregation and analyses PA data exchanged between the field and data repositories.

The conferences, proceedings, journals, and books provide effective forums for disseminating original and fundamental research and experiences in the fast-growing area of PA [58].
