How products that are the same are advertised differently

For all companies, advertisements are a subject of which need constance surveillance and updating, even if the advertsement out for a product is a massive hit, after a few weeks the company will need to make a new one so that the product and branding doesn't become boring and predictable. A fine example of this would be the surreal Cadburys adverts which have been produced and pput on to our screens rather recently. All the advertisements are of Cadburys dairy milk, the flagship product of the cadburys industry and despite the success of say the gorilla drumming to Phill Collins, they still produced another advert to neutralize the threat of the advert and branding going stale.

Here are pictures of the three recent adverts which have carried the quirky and imaginative theme of cadburys at this given time:

The eye brows advert for cadburys

The cadburys Gorilla advertisement

The racing cadburys advertisement
These are fine examples of how companies will stick with a similar theme for a log ruun of advertisements and it's something of which i'm going to do.

Another example of an even longer running themed advert is the Gary Lineker comic walkers crisps advertisements. These advertisements have been going for absolute years and each time they're just the same except with a different concept which enlightens the audience to something supposedly new and fresh. The walkers crisps franchise has been going for years so it just shows that perhaps sticking to a similar formula is the way to go.
Here are some pictures of the Walkers crisps advertisements over time:
