As of 2023[update] its CEO is Dave Watson, its chairman is Brian L. Roberts, and its CFO is Catherine Avgiris.

"[13] Comcast is the largest provider of cable internet access in the United States, servicing 40% of the market in 2011.

[17] When the combined company Excite@Home filed for bankruptcy in 2002, Comcast moved their roughly 950,000 internet customers completely onto their own network.

[18] Along with the price of internet subscriptions, Comcast charges users an additional $15.00/month to rent a cable modem.

The U.S. Federal Communications Commission (FCC) required this budget service as a condition for allowing Comcast's acquisition of NBCUniversal in January 2011.

[24] In March 2014, as he met with FCC concerning the Time Warner Cable merger, Comcast vice president David Cohen told reporters that the internet essentials program will be extended indefinitely.

Users on the "Performance" tier or higher receive unlimited usage of these hotspots after signing in with their Xfinity Account.

[36][37] Comcast has received criticism for this practice, with critics arguing that the company was abusing customer resources (including bandwidth and electricity) to provide services for other customers, as well as concerns regarding security, and liability for actions performed by users while connected to these home hotspots; in 2014, a proposed class action lawsuit was filed in California, citing violations of the Computer Fraud and Abuse Act and similar state laws for these reasons.

Comcast defended the service by stating that the public Wi-Fi is firewalled from devices connected to the in-home network, was designed to have minimal bandwidth impact to "support robust usage", and that customers would not be liable for the actions of other users, as abusers can be traced by means of the Xfinity account they used to sign into the network.

[40] In the wake of Hurricane Irma, all Xfinity WiFi hotspots in Florida were opened to non-Comcast subscribers.

[43][44] In September 2007, Comcast spokesman Charlie Douglas said the company defined "excessive use" as the equivalent of 30,000 songs, 250,000 pictures or 13 million emails in a month.

[52] On April 27, 2016, Comcast announced that it would raise its data threshold in trial markets to 1 TB by June 2016; the company stated that "more than 99 percent of our customers do not come close to using a terabyte."

As previously, a $10 overage fee is charged for every 50 GB above the limit, and customers can purchase an add-on for "unlimited" data, but its price was increased to $50.

[53] In October 2016, Comcast announced that bandwidth thresholds would be implemented in the majority of its markets (outside of New York and the northeast) beginning November 1, 2016.

[57] In September 2007, a rumor emerged among tech blogs that Comcast was throttling or even blocking internet traffic transmitted via the BitTorrent protocol.

The court suggested instead of its current framework, the FCC move to a common carrier structure to justify its enforcement.

[66] As of February 2014, the FCC has announced a new justification,[67] but avoided the more extensive regulation required by the common carrier framework.

[89] Comcast also charges a Regulatory Recovery Fee of varying size(s) with their Digital Basic cable subscription in order to "recover additional costs associated with governmental programs".

It features wider support for internet content and video streaming apps, and a remote control with voice recognition input.

The service is marketed as an alternative to the full Xfinity TV service for cord-cutters[101][102] In October 2021, Comcast launched XClass TV, a line of Hisense-manufactured smart TVs based on X1, and sold exclusively through Walmart; they marked the first X1-based product to be sold directly at retail to consumers.

[105][106] Beginning in the mid-2000s, the prices of retransmission fees, requirements for cable companies to retransmit television broadcasters content, have become more expensive.

The U.S. Federal Communications Commission then reviewed its rules for broadcasters and distributors to make any possible changes to them in response to the high-profile blackouts.

[108] Comcast has had ten year agreements with CBS[109] Disney,[110] and Fox Broadcasting Company[111] for distributing and reproducing content.

In March 2011, Comcast created an indirect sales channel called the Solution Provider Program, a comprehensive indirect channel program that enables telecommunications consultants and system integrators to sell Comcast's services such as Business Class Internet, Voice, and high-capacity Ethernet services to small and mid-market businesses.

The program offers recurring commissions for sales partners based on monthly revenue, and Comcast will provide, install, manage and bill for these services.

[127] Xfinity and its parent company, Comcast, were sued in August 2016 in King County Superior Court by the State of Washington (AG Ferguson, Washington's Attorney General) for 100 million dollars[128] over claims that Comcast violated the state's Consumer Protection Act 445,000 times over its Service Protection Plan[129] by over charging for call service fees, knowingly using improper credit screening practices, and by lying about the costs of its Service Protection Plan to 49,660 customers on support calls.

It accused Washington of only "listening to 150 calls when we gave 4,500 of them",[131] and said that "customers receive an email confirmation when they sign up for the protection plan".

The lawsuit lasted until June 2019, when a King County court judge, Judge Timothy Bradshaw, ruled in favor of Washington State and against Comcast, ordering Comcast to pay 9.1 million dollars in penalties in addition to providing restitution to customers within 60 days.

This service is not available to all households as it requires installation of a fiber optic local loop, as DOCSIS isn't capable of 10 gigabit end-user speeds.
