You said it right there. Look further down the financials. Comcast net income is $1.8B, Google is $3.4B. Time Warner Cable (I assume that's what's meant by TMV, although their ticker is TWC) is $0.4B.
But net income isn't a good comparison, because things like spending on R&D and infrastructure are subtracted before you get to it; they don't come out of net income, they come out of gross profits. So Google does not have significantly more funds available for those things than Comcast does; it has less.
