Keeping in mind too ...
- Where does our SLF post those holiday snaps that inspire their friends and associates to travel with us? Facebook (and instagram -- same company)
- Where do the travel bloggers post links to their videos, photos, and blogs that promote travel? Facebook.
- Where do the travel agents post advertising promoting their services? Facebook
- Where do our airlines post advertising to promote their services on their websites? Facebook.
- Where do businesses start their advertising? Facebook.
Facebook offers incredibly targeted advertising - without it I suspect that more than a few of us would be out of a job due to decreased demand for bums on seats.
