This is cable industry trade data not really something intended for the general public. Dollar amounts aren't going to provide the context required to understand this data. For example over the last 5 years most cable MSOs have gone mostly/all digital which has reclaimed hundreds of megahertz's of spectrum. As a result spending on plant/infrastructure upgrades has slowed. The costs of the digital migrations wouldn't be classified as broadband investments even though it's directly related. Also in this time span most cable providers completed their transition to DOCSIS 3. Big upfront cost but less expensive to scale out over time. Soon they will have another big upfront cost for the DOCSIS 3.1 transition.
