Google's access to personal data through products such as Gmail and Google Checkout also raises privacy concerns, Lee said.
"Google's powerful position as an Internet gatekeeper reduces the company's incentive to compete with other search engines by providing enhanced privacy protection for consumers," Lee said.
In the broadband industry, the subcommittee will look into the link between competition and net neutrality, Kohl said.
"Maintaining competitive choices in this industry is crucial to consumers and the health of the national economy," he said in the press release. "We will also examine the issue of network neutrality principles and monitor whether consumers continue to have the freedom to access the internet content they wish without interference from their Internet service provider."
Other priorities for the subcommittee include competition in the cable and satellite TV industries, the airline industry and the pharmaceutical industry, Kohl said.
