Time Warner Cable Internet is a US Internet service provider (ISP) which provides cable Internet service over DOCSIS-compatible modems. A division of Time Warner Cable, it also contracts its service to other cable providers, often in competition with ISPs owned by local telephone companies. Time Warner Cable Internet was previously known as Road Runner High Speed Online.

Road Runner service was first launched with a 1995 market test in Elmira, NY, under the banner Southern Tier On-Line Community. Later it became known as LineRunner (a moniker subsequently employed by VoIP service), before Time Warner Cable adopted the Road Runner brand name.

Road Runner High Speed Online employed the Road Runner character from the Looney Tunes/Merrie Melodies cartoon series as its mascot and brand name. However, in 2012, it was rebranded as simply Time Warner Cable Internet, dropping the Road Runner branding which Time Warner Cable had to license from the now-unaffiliated Warner Bros.
With the completion of DOCSIS 3.0 rollout in 2012, Time Warner Cable Internet has standardized the Internet tiered service data rates across most of its franchises, although some minor regional variations might still exist.
The maximum advertised speeds for these services are:

  • Basic: 3.0 Mbit/s / 1.0 Mbit/s
  • Standard: 15 Mbit/s / 1 Mbit/s
  • Turbo: 20 Mbit/s / 2 Mbit/s
  • Extreme: 30 Mbit/s / 5 Mbit/s
  • Ultimate: 50 Mbit/s / 5 Mbit/s

The Extreme and Ultimate service tier offerings were created in 2009, and became available in markets as Time Warner Cable rolled out DOCSIS 3.0 upgrades nationwide.

Previous service tiers that have been retired were Lite and Turbo Plus. Lite was intended as a low-cost, low-speed (1 Mbit/s or less) alternative to DSL services, which, at the time, were generally cheaper than cable internet service, but also slower. Turbo Plus was a faster speed tier than Turbo, but slower than the future DOCSIS 3.0-based tiers, and as Extreme and Ultimate tiers became available, Turbo Plus was dropped.
