Broadband penetration in the US broke 60% for the first time in August. In August 2005, U.S. broadband penetration jumped 1.4 percentage points to 61.32% among active Internet users. According to a recent study however, broadband growth in the US is slowing down. Meanwhile, 74.5% of wired Britons enjoy a broadband connection at home. The charts below, derived from Nielsen//NetRatings and Pew Internet data, show trends in connection speeds to the Internet for users in the United States.*
Home users in the US set a milestone in August, passing the 60% broadband penetration mark for the first time. Narrowband users (56Kbps or less) now comprise 38.68% of active Internet users, down 1.4 percentage points from 40.08% in July 2005 (see Figure 1).

In August 2005, broadband penetration in US homes rose 1.4 percentage points to 61.32%, up from 59.92% in July. This is the first time broadband penetration has exceeded 60% in the US among active Internet users. This increase of 1.4 percentage points is above the average increase in broadband of 1.14 points per month over the last five months. At the current growth rate of over 1.1 percentage points per month, broadband penetration among active Internet users US homes should break 70% by January of 2006 (see Figure 2). This assumes that the broadband adoption rate will not decrease, as the report below concludes.

We asked Bruce Leichtman about the significance of this major milestone.
"Broadband is one of the fastest adopted products/services in the history of this country, and the US leads the world in the number of broadband subscribers. The DSL and cable operators have been aggressively pushing the market over the past year and half, while it may be difficult to keep up the pace set over the past 18 months, there is still plenty of opportunity to keep the net adds running at a very healthy rate over the next 4-5 years." - Bruce Leichtman of LeichtmanResearch.com
Most workers in the US enjoy high-speed connections to the Internet. Most use a high-speed line such as a T1 connection, and share bandwidth between computers connected to an Ethernet network. The speed of each connection decreases as more employees hook up to the LAN. As of August of 2005, of those connected to the Internet, 85.46% of US users at work enjoy a high-speed connection, up 3.82 percentage points from the 81.64% share in July. At work, 14.54% connect at 56Kbps or less (see Figure 3).

According to a recent report by Pew Internet & American Life Project broadband adoption in the United States is slowing down. John Horrigan, Pew's Director of Research, compared national surveys of Internet users in 2002 to 2005. Horrigan found that the intensity of Internet use (a product of connection speed and years of online experience) drives the number of online activities people perform, which in turn drives the adoption of broadband (processing more bits). The two factors (speed and experience) vary in their influence of use over time. In 2002 both having broadband at home and Internet experience were significant factors in Internet usage. However, in 2005 only having broadband at home had a significant influence on intensity of Internet usage (see Figures 4 & 5). This implies that there is little pent-up demand for broadband at home. We talked to John Horrigan about his findings.
"We don't see a large influx of new Internet users in the U.S. anytime soon. 6% of the Internet's population are new users, and only 23% of them are on broadband, about half the overall rate. Current dialup users are less engaged in the Internet than past dialup users."
Dialup users today are older, less affluent, and less educated than their 2002 counterparts. With switching costs still high, today's dialup users are less likely to switch to broadband than they were in 2002. The report concludes that slowing broadband growth may add pressure on policymakers to take a bold approach (municipal wireless broadband networks for example) to catch up to leading broadband countries like Korea or Canada.

*Note that Nielsen//NetRatings new NetSpeed report differs from the previous Web connection data in two ways. First NetSpeed determines the connection speeds of the Digital Media Universe, which combines Web traffic, Internet applications and proprietary channels. The old Web connection data was based solely on Web traffic. The other difference is that the old Web connection data was based on panelists where the linespeeds are known. Since linespeeds don't change often, if a panelists has an unknown linespeed, their previous month's speed is taken.
