The current ident shows hippos swimming round in a circle. This is to continue the theme of the circle or a globe which has been the symbol of the BBC from the very first ident. All through the years the globe has appeared in every BBC ident shown in different and clever forms. There are a number of Christmas idents over the years which have continued the circle theme with a Christmas flavour. For example, there have been large snowballs, snowflakes, snowmen and penguins skating is a circle all of which embody the round theme. The font has always been in capitals and bold to be easily read and recognised. The circular ident is also used for the other BBC channels like BBC2 BBC3 and BBC4. The circle could also show the BBC is a trustworthy channel with evolving news and information.
