YouTube TV will be rolling out to an additional 95 markets in the U.S., almost doubling its coverage. The streaming video service already covers the top 100 markets in the country, and the expansion will enable it to reach more than 98 percent of households in the U.S., YouTube said. The rest will follow shortly thereafter. There are roughly 120 million TV households in the United States, but only about 108 million households have broadband, which is a prerequisite for YouTube TV, noted Michael Goodman, research director at Strategy Analytics.
