What is the etiquette of the digital age? And what are regarded as good manners in cyberspace?
A survey among office workers across the United Kingdom is designed to help businesses formulate guidelines on what is and what is not acceptable in the world of modern communications.
The survey, carried out by business communications provider NTL: Telewest Business, suggests that almost one-half of UK office workers would consider it rude not to have received a reply to an email within a morning.
And five per cent of people would consider it rude if they had not received an email response within five minutes of sending it.
The survey claims that two out of every five people would expect a response to a text message within an hour before considering it rude, and almost a quarter of the people questioned expect a response within five minutes to an instant message.
Stephen Beynon, managing director of NTL: Telewest Business, said: "The British are renowned for their manners, so it is important that as and when these tools become more widely known, businesses give guidelines to their staff on how to use them efficiently.
"If businesses fail to tackle this head-on, they risk damaging relationships with suppliers, partners and clients alike."
The survey found that email was the most highly regarded tool in the office, with 78 per cent of the respondents claiming they could not live without it in the workplace.
Nearly one-third of the respondents said they still use fax and letters every day.
The study, known as Digital Etiquette, was carried out by the research company TNS who surveyed more than 1,400 office workers, aged 16-64 across the United Kingdom in January on behalf of Telewest Business.
Meanwhile, Telewest has launched new high-definition TV services in the West Midlands.
The cable firm is making its new personal video recorder - called the TVDrive - available to more than 430,000 homes in the region.
The HD programmes are offered via the cable company's TV-on-demand service, called Teleport, which provides instant access to a huge library of viewing at the touch of a button. HD programmes have four times as many pixels as standard TV broadcasts, meaning crystal clear pictures, even on the biggest plasma and LCD TVs.
Philip Snalune, managing director consumer products, ntl Telewest said: "HDTV takes the viewing experience a significant step beyond standard digital television and has to be seen to be believed.
"It's set to become this year's must-have home enter-tainment experience and Telewest customers in Birmingham are the first in the UK to get access to it.
"We'll add more choice of high definition viewing this year and combining TVDrive with our existing on-demand service we're giving customers TV on their terms.
"Viewers no longer need be tied to the schedule and can now watch what they want, when they want, with unparalleled picture quality."
