Big technology companies are being dragged in front of Congress to answer tough questions about their impact on the 2016 presidential election, and their market power is under increasing scrutiny.

If revenue growth is a good indication of giving the public what it wants, customers appear to love what the biggest technology companies are offering, whether it’s cheap online storage, clothing or a social network, and the party isn’t slowing down.
