Pewdiepie vs T-Series

Pewdiepie vs T-Series is a currently an ongoing 'subscriber count competition' on Youtube, driven by Pewdiepie fans who are desperate to keep their boi's channel on top. With the recent rise of the meme 'Sub to Pewdiepie', Pewdiepie has raced ahead of T-Series in terms of subscribers. Now, you, as a T-Series fan is furious, so you get the fanbase together and start a whole lot of advertising and shoutouts on Youtube, while also introducing the meme of your own - 'Sub to T-Series'.

You know that:

• The memes each increase the rate of subscriptions by 20%.

• Advertising/shoutouts increases the rate of subscriptions by 30%.

• The rate of subscriptions is proportional to the number of subscribers at that time.

If your plan is successfully carried out, will T-Series eventually overtake Pewdiepie?

• Pewdiepie was created in April 2010, while T-Series was created in March 2006.

• You begin taking action in December 2018.
