what would be the optimal method, cost, and benefit to make certain online content "free" - in other words, ensuring no data charges on certain websites or content?
for example, corporate websites are very specific, and corporates should and can only benefit from increased traffic on their sites, such that they might consider subsidizing at least data costs, to increase potential traffic to their sites.
furthermore, particularly in developing countries, making certain online content "freely" available - subsidizing the data costs - should have developmental benefits. an example might be wikipedia.
subsidizing certain online content might be more economical and effective that outright free internet.
should internet usage of parts thereof be subsidized? what should be targeted? what would be the costs? what would be the benefits?
