WASHINGTON (Reuters) - The House of Representatives Judiciary Committee expects to have a final report on its probe of big technology companies and their potential breaches of antitrust law, by the “first part” of next year, the chair of its antitrust panel said on Friday.

The committee has received tens of thousands of documents from Facebook Inc, Alphabet’s Google, Amazon.com Inc and Apple Inc and is expecting more material in the coming weeks, Representative David Cicilline told reporters.

“Our hope is to conclude our evidence collection end of this year, beginning of next year with the idea that we will have a final report, instead of recommendations in the first part of next year,” said Cicilline, a Democrat.

He made the comments at a hearing to discuss the effect of consumer data collection by big technology platforms on online competition. Rohit Chopra, Commissioner of the Federal Trade Commission, as well as experts from Harvard Kennedy School and the American Enterprise Institute participated in the hearing.

Vast troves of consumer data collected by big technology companies allow them to gain a competitive edge and pose a threat to competition by creating entry barriers, Chopra said.

Personal data is powering the dominance of tech companies that offer basic services for free, which are ultimately not free, he added.

Chopra also said small fines and financial penalties will not be enough to address concerns about the power of big tech firms, adding that regulators will need to take a closer look at that.

For example, earlier this year the FTC fined Facebook Inc $5 billion over online privacy. Chopra voted against that decision.

There are several probes at the federal, state and congressional level aimed at determining if big technology companies use their considerable clout in the online market illegally to hurt rivals or otherwise break competition law.

Once lauded as engines of economic growth, these companies have increasingly been on the defensive over their outsized market influence. Politicians including President Donald Trump, consumers, other firms and regulators have criticized that power.
