"We've been bundling video successfully and creatively for 60 years," Roberts said on Tuesday, referring to Comcast's long history as a cable television provider that offered bundles of broadcast, news, entertainment and sports channels at different price points. Like other companies, Comcast has seen an erosion of its traditional pay TV offering as customers ditch expensive cable bills for cheaper streaming options. Comcast has embraced the trend by forming a joint venture with peer cable operator Charter called Xumo, which is developing and deploying a streaming TV platform that integrates linear content channels with on-demand services through a dedicated device called the Xumo Stream Box and related Xumo-powered smart TV sets. Comcast is also reaching budget-conscious consumers who still want a pay TV package at an affordable price.
