[7][8] On January 24, 2000, Comcast Commercial Online announced a partnership with click2send.com (TM), Inc.[9] The stock of the @Home Network collapsed during the mid-2000 dot-com bubble, bankrupting @Home, and Comcast moved subscribers to their own network instead of selling though a third party.

[20][21] By 2010, the company's investment in "massive amounts of fiber" for its cable television operations enabled it to include medium-sized businesses of 20 to 250 employees.

[37] In February 2014, Comcast Business was recognized as the fastest growing company based on 2013 carrier Ethernet provisions.

[38][39] In 2013, Stemper was given a Vanguard Award from the National Cable & Telecommunications Association in the "operations and management" category.

[34] According to a mid-year 2014 leaderboard report on Ethernet by Vertical Systems Group, Comcast Business grew more than any other U.S. provider, rising to sixth place (from eighth).

Bill Stemper, the president of Comcast Business, said buying Blueface would give his division's customers "access to industry-leading audio and video tools to connect employees across devices and locations".

[49] In addition to their standard DOCSIS service, Comcast also offers SD-WAN via Comcast Business ActiveCore,[50] and Carrier Ethernet services for businesses, which provide symmetric download & upload links with speeds ranging from 2 Mbit/s to 10 Gbit/s, in select cities.
