You can't really compare headline profits without seeing the full breakdown of revenue and expenses that led to those results. For example Visio's hardware side could be reinvesting vast sums of revenue back into TV R&D. Or they could have invested in upstream component manufacturers. Maybe they spent a large amount on recruiting new staff. All those expenses are deducted before profit. Meanwhile the ad division might have made no investments for the future and took the tax-inefficient choice to show a large profit instead.
