Watts family
When "EastEnders" began in 1985, the soap focused primarily around the affairs of three families: the Beales, Fowlers, and Watts. However, much of the show's early success stemmed from the drama surrounding the Watts, especially the antics of Den, who as owners of the Queen Vic pub (the show's most prominent set) were usually in the limelight. This prominence, at a time when "EastEnders" was at its most prolific in terms of both the media and audience, meant the Watts became perhaps "EastEnders" most eminent family and the characters known even to those who did not watch the show. Such was their success that producers went ahead with an experimental episode format centring on just Den and Angie, during which Angie lied about having cancer; so successful was the airing that it has since been repeated, and the format expanded to include "three" and "four-handers" (between 3 and 4 characters). Such episodes are highly prestigious and feature only the most popular and prominent characters in the show; thus, all the Watts, aside from Vicki, have featured in such episodes.
Soap opera
The 1986 Christmas Day episode of "EastEnders" is often referred to as the highest-rated UK soap opera episode ever, with 30.15 million viewers (more than half the population at the time). The figure of 30.15 million was actually a combination of the original broadcast, which had just over 19 million viewers, and the Sunday omnibus edition with 10 million viewers. The combined 30.15 million audience figure makes the aforementioned Christmas Day 1986 episode of "EastEnders" the highest-rated single-channel broadcast in the history of UK television. Overall it ranks third behind the 1966 FIFA World Cup Final (32.3 million viewers) and Princess Diana's funeral in 1997 (32.1 million viewers) which were transmitted on both BBC One and ITV.
