A good example of this can be seen from the encyclopedia. Encyclopedia สารานุกรมบริตานิกาhas been continuously published for nearly 250 years (since 1768). although encyclopedic Britannica content has existed digitally since 1981, it was not until the advent of wikipedia in 2001 that open access to encyclopedia content became available to users worldwide. Access to encyclopedia Britannica remains restricted to a limited number of paid subscribers, thus,although the technology and digital content was available to enable free access to encyclopedic content, ideological roadblocks prevented this from happening.It was not until these ideologies had been overcome that humanity was empowered to create what has become the world's largest, most up-to-date encyclopedia
