Absolutely. Berkshire holds sizable positions in companies that spend significant amounts of money on marketing and website design.
What I find fascinating is the absolute simplicity. People do not buy shares in BRK for fancy design or cutting-edge tech solutions. They buy shares because Warren Buffett has return 586,000% gain over the life of the fund (i.e. 1964 to present).
Berkshire, with Warren Buffett at the helm, does one thing really well: make money. That is their product and that is all they focus on.
