Nearly 7 of 10 U.S. households are online, and 60 percent of them - or some 40 percent of all U.S. households - have high-speed internet access, according to a study from Leichtman Research Group, reports Internet Retailer. In the first quarter of the year, an additional 3.06 million high-speed subscribers were signed up - a quarterly record - by the country's 20 largest cable and DSL providers (which account for 94 percent of the market).

Cable accounts for nearly 25.8 million broadband subscribers, and DSL about 20.2 million, according to MediaPost. (See more data in previous coverage, here.)

The top five states in residential broadband penetration were Connecticut, New Jersey, Hawaii, Massachusetts and California; the bottom five were Mississippi, South Dakota, North Dakota, Kentucky and Montana.
