BBC Text was considerably more advanced than Ceefax, in that it offered a richer visual interface, with the possibility of photographic images and designed graphics (as opposed to Ceefax graphics which were composed of simple blocks of colour). BBC Text also enabled channel association, the ability for the user to retain their selected television channel visible in one section of the screen whilst viewing the text service, in contrast to Ceefax, which could only be viewed as a full-screen display, or as a semitransparent overlay above the television picture. The original text service had no return path, this being made available in later phases.
BBC Text pioneered an early form of "on-demand" interactive television, called Enhanced TV. During the 1999 Wimbledon Championships, the BBC presented a service which allowed viewers to select a video stream of different matches, and access additional information such as player profiles, scores and interactive quizzes. Although the experimental service was publicly available, there were no digital set-top boxes or receivers available on the market which could decode the signal and the service was only presented to the public via BBC demonstrations using prototype receivers.
The various services all took on a common interface device, an "i-bar" branded with the BBCi logo, which sought to emphasise the brand across different technologies by providing similar navigation. For example, the BBC website, which had previously been called BBC Online, took on the BBCi brand from 2001, displaying an i-bar across the top of every page, offering a category-based navigation: Categories, TV, Radio, Communicate, Where I Live, A-Z Index, and a search. Similarly, BBC interactive television services all offered a horizontal i-bar along the bottom of television screens, with four colour-coded interactions linked to the four colour buttons on TV remote controls.
After three years of consistent use across different platforms, the BBC began to drop the BBCi brand gradually; on 6 May 2004, the BBC website was renamed bbc.co.uk, after the main URL used to access the site. Interactive TV services continued under the BBCi brand until late 2008.
Today, the broadcaster's online video player, the BBC iPlayer, reflects the branding legacy by retaining an i-prefix in its branding.
In November 2008, the BBC celebrated 10 years of the digital interactive TV service.
In September 2005, BBCi launched an update to the interactivity available from the BBC's Radio channels on Freeview. Originally only Radiotext was available. After the update, users could access information about the programme, schedules, news, sport and weather. From 2005, Freeview users could access the CBBC Extra video stream.
The same team behind the BBC's digital text service also launched the early incarnations of the BBC's Interactive Wimbledon and Interactive Open Golf services in 2000, which were awarded an Interactive BAFTA that year.
The News Multiscreen was removed from the digital service in October 2009, to make room for future Freeview HD broadcasts.

Page numbers were introduced in 2004 to aid navigation, with 3-digit page numbers matching with those of the analogue Ceefax in 2006. Pages exclusive to digital are given a four digit number.
The Teletext service from the UK commercial broadcasters had stopped supporting the old boxes in 2005. As of 2010, the ONdigital boxes only load pages 100 and 199 and some interactive services that use channel 301, if any other page is loaded it exits the service.
Usage of these boxes dwindled further as technology developed. They used "original" technology and as such were not upgradable. Following each regional changeover to full digital TV broadcasting, the remaining units are no longer of use, as they do not support the '64QAM broadcast mode' introduced across the UK as part of the 'digital switchover'.
