I was interested to see some overseas companies shed up to 25% of their share value last week. Idearc in the US and Yell in the UK are among those affected. I see this as a reminder to ensure balance in business. Newsagents risk pain by depending on one supplier, one product or one category too much. This is why we need balance. It’s why smart newsagents are moving into new product categories which compliment their existing offering.
