In the UK, (and I believe in Europe) Line 22 is becoming the de-facto standard, for EIA 746 type VBI insertions. Some broadcasters (such as the BBC) would find difficulty using any other line. The relationship with UK style Teletext (and URL's that might be carried in teletext) is unclear. The transmission and interpretation of events in the digital domain is still in need of better definition. The UK mandates DVB rather than ATSC, and there are some hints how to do this for the MHEG regime, but further definition is needed. The immediate applications we see are for program adjunct material, and for EPG use.
