We got to go behind-the-scenes at the Cadbury factory in Bournville and find out how much things have changed.
In 2010, American owner Kraft won a bitter takeover battle and the parent firm of Cadbury Mondelez International invested £75 million in Bournville.
Before four new lines were upgraded, it cost three times more to produce a chocolate bar in Birmingham than in Europe.
If the West Midlands factory was to survive, things had to change meaning newer machines but fewer people.
Some product changes over the last few years:
In 2013, Bournville chocolate, one of the companies oldest brands was removed from the Heroes tubs.
In 2014, Cadbury announced on Twitter that their chocolate coins were being discontinued because they are not as profitable as other products.
In 2015, the parent firm of Cadbury, Mondelez International, replaced the Dairy Milk shell on a Creme Egg with one made from a standard cocoa mix.
Last year, the Time Out bar disappeared and was replaced with a slimline single-finger version called the Time Out Wafer.
In 2016, Cadbury did announce it was relaunching its Tiffin bar after an online campaign by fans.
How many bars of chocolate are made at Cadbury?
Why are Freddos getting more expensive?
Remember when that little frog shaped bar used to cost you 10p? Well it will now cost you 30p. The price of this Cadbury favourite seems to have risen over the years and we wanted to know why.
Glenn Caton, the Northern Europe President, explains why the price has gone up for consumers.
Are any classics going to make a comeback?
They were keeping tight lipped about new products in the pipeline only telling us that there is “new innovation to come”.
So we also asked whether any old favourites would reappear?
Apparently heritage brands like Fuse always get quite a few mentions on social media but it depends if the demand is high enough and the cost of production can match that.
